* autobuild: Fix two issuesChris Dickens2020-01-261-2/+2
| | | | | | | | | | | The test for defining the automake conditional for the poll implementation was keying off of the threads variable, producing incorrect results for Cygwin. A simple typo in the Makefile causes a build failure when cross-compiling for Windows. Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* configure.ac: Cleanup and refactoringChris Dickens2020-01-241-183/+190
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the formatting consistent across the entire file. In particular: - Always quote strings whose values are derived - Use tabs consistently - Wrap all arguments with square brackets Replace the use of '-a' with '&&' to be more portable. Rearrange some of the feature checks to be conditional upon the platform or backend. For example, there is no need to check for nfds_t on Windows because poll() doesn't exist there. Similarly we now only check for timerfd on Linux and Solaris. This translates into slightly faster configure times. Explicitly define tokens for both the poll and thread implementations. This makes the preprocessor conditionals much nicer since it is not necessary to enumerate all possible OS_* tokens. Also replace POLL_NFDS_TYPE with a proper typedef that is based on the availability of the nfds_t type. Migrate to config definition names that are more consistent with autoconf. The check for timerfd actually verifies the presence of the library function instead of just the header definitions, and the token USBI_TIMERFD_AVAILABLE is now HAVE_TIMERFD. Similarly the check for syslog results in a definition of HAVE_SYSLOG. Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* Windows: Drop support for Windows XPChris Dickens2020-01-211-2/+1
| | | | | | | | | XP is nearly 20 years old and there are hoops we jump through to keep supporting it. Time to say goodbye and simplify some things. Closes #267 Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* Add Null POSIX backendPino Toscano2019-12-281-1/+12
| | | | | | | Add a simple null backend for POSIX platforms that reports no available devices, and provides no capabilities. Make use of this new backend on all the OSes without an existing backend, so libusb can be built even on OSes without USB support.
* Unix: fix library version for next releaseLudovic Rousseau2019-08-091-1/+1
| | | | | | | | | | | | | | | | https://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html says: 4. If any interfaces have been added, removed, or changed since the last update, increment current, and set revision to 0. 5. If any interfaces have been added since the last public release, then increment age. So both current and age must be incremented.

* configure.ac: fix detection of clock_gettime libraryBaruch Siach2018-10-221-1/+1
| | | | | | | | | | | | | | | glibc before 2.17 requires link with librt for clock_gettime(). The AC_SEARCH_LIBS check in configure.ac should detect this dependency. Unfortunately commit cb77a25e51 (configure.ac: Remove obsolete AC_ERROR and make formatting consistent) inadvertently renamed to clock_gettime2, thus breaking librt detection. Restore the correct clock_gettime() name. Closes #439 Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>

* linux: Mark internal file descriptors as CLOEXECChris Dickens2017-02-281-1/+2
| | | | | | | | | | | | As a library, libusb should take care to be as friendly as possible with various use cases. One such way is to ensure that internal file descriptors have the CLOEXEC flag set, thus allowing processes to do a fork() + exec() without leaking libusb's file descriptors to the child process.

* configure.ac: Remove obsolete AC_ERROR and make formatting consistentChris Dickens2017-02-201-40/+40

* configure.ac: Clean up styleChris Dickens2017-01-121-24/+24
| | | | | | | | | | For consistency, only use quotes for strings where variables are interpolated. Also make the check for syslog capability dependent upon whether system logging has been enabled. Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* core: Remove use of gettimeofday()Chris Dickens2017-01-121-10/+4
| | | | | | | | | | | | | | | | | Prior to this commit, gettimeofday() was being used for timestamps in debug messages. This function has been marked as deprecated in the latest POSIX specification and furthermore is not supported on Windows, thus requiring our own implementation as usbi_gettimeofday(). This commit changes the logging code to obtain timestamps using the clock_gettime() function provided by the backend. The implementation of usbi_gettimeofday() for Windows was actually equivalent to that of the USBI_CLOCK_REALTIME implementation for clock_gettime(), so this eliminates code duplication. In addition, the USBI_CLOCK_REALTIME implementation has been updated for Windows to leverage the timespec_get() function available in VS 2015 and later.

| | | | | | | | | | | | This commit bumps the minimum autoconf version to 2.69. This only affects maintainers and will ensure libusb tarballs have up-to-date configure scripts. At the same time we are removing the AM_MAINTAINER_MODE macro as even its creator recommends against using it. Closes #122 Signed-off-by: Nathan Hjelm <hjelmn@me.com>

* Misc: Simplify Haiku build and fix broken parallel buildChris Dickens2015-12-171-1/+1
| | | | | | | | | | | | | | | | | | The Haiku build was previously being done as a nested package due to its C++ requirement, but for some reason setting SUBDIR in an automake conditional breaks parallel builds. To fix this and simplify the Haiku build process, this commit adds an unconditional check for a C++ compiler using AC_PROG_CXX and builds the Haiku sources as part of the main libusb project. Note that AC_PROG_CXX itself does not cause the configure script to fail if a C++ compiler is not found. Therefore on non-Haiku platforms there is no requirement to have a C++ compiler installed in order to build libusb. Closes #121 Signed-off-by: Chris Dickens <christopher.a.dickens@gmail.com>
* Remove -c flag. Erroneous output caused on androidVenkatesh Shukla2015-03-011-3/+0
| | | | | | | | | | | While cross-building for android, the -c flag was causing errors. This -c option ends up in Libs.private of libusb-1.0.pc file. On its usage, it is interpreted as "Compile and assemble, but do not link" option of gcc. Usage of -c in this way might be unintended. Hence, removing this option.

* openbsd: Split openbsd backend into separate openbsd and netbsd backendsHans de Goede2013-08-211-6/+15
| | | | | | | | | | | Note the new netbsd_usb.c is an unmodified copy of openbsd_usb.c with s/obsd/netbsd done on it. The reason for this split is that the openbsd developers have been working on various improvements for their userspace usb support, and adding support for those means breaking netbsd support, by giving netbsd its own backend we can add support for the openbsd improvements without breaking netbsd support.

* Core: Add compile time option to use native OS logging facilityToby Gray2013-08-091-5/+20
| | | | | | | | | | * This change makes it easier to debug issues in UI applications which don't necessarily have a console connected to stderr. * Outputting to the debugger shouldn't occur in normal situations so this change has to be explicitly enabled by a build-time config flag. * Uses OutputDebugString() on Windows platforms or the syslog facility on other OSes, if available. * Also align the report of configure defaults to autotool's.
* Add checks for headers needed by linux/netlink.hNathan Hjelm2013-07-301-1/+9
| | | | | | | | These headers are required by netlink.h. I am not sure how this worked at all. It certainly doesn't work with older versions of Linux 2.6. References #124.
* configure: Fix --enable-udev help textHans de Goede2013-05-161-1/+1

* Add hotplug support to the Linux backend.Nathan Hjelm2013-05-151-1/+14
| | | | | | | | | | There are two ways to configure hotplug support for Linux: udev, and netlink. It is strongly recommened that udev support is used on systems that utilize udev. We reenforce this recommendation by defaulting to --with-udev=yes at configure time. To enable netlink support run configure with --with-udev=no. If udev support is enabled all device enumeration is done with udev. Signed-off-by: Hans de Goede <hdegoede@redhat.com>

* Windows: Enable MinGW and MSVC DLL interchangeabilityPete Batard2012-06-081-0/+2
| | | | | | | | | | * Because we use the WINAPI calling convention, the def file MUST have the @n aliases. There is no way around this as MinGW's .o use decoration always for __stdcall, which can't be turned off. * dlltool must therefore be invoked to create a proper import lib from the .def, using the --kill-at option. * To do that, a CREATE_IMPORT_LIB autotools variable is introduced. * Note: the .def file is currently maintained manually.
