* copyright: update all copyright lines and remove year rangesDaniel Stenberg2023-01-031-1/+1
| | | | | | | | | | | | - they are mostly pointless in all major jurisdictions - many big corporations and projects already don't use them - saves us from pointless churn - git keeps history for us - the year range is kept in COPYING checksrc is updated to allow non-year using copyright statements Closes #10205
* build: assume errno.h is always availableJay Satiro2022-12-071-1/+0
| | | | | | | | - Remove errno.h detection from all build configurations. errno.h is a standard header according to C89. Closes https://github.com/curl/curl/pull/9986
* build: assume assert.h is always availableJay Satiro2022-12-071-1/+0
| | | | | | | | | | | | | - Remove assert.h detection from all build configurations. assert.h is a standard header according to C89. I had proposed this several years ago as part of a larger change that was abandoned. Ref: https://github.com/curl/curl/issues/1237#issuecomment-277500720 Closes https://github.com/curl/curl/pull/9985
* Makefile.mk: portable Makefile.m32Viktor Szakats2022-11-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update bare GNU Make `Makefile.m32` to: - Move objects into a subdirectory. - Add support for MS-DOS. Tested with DJGPP. - Add support for Watt-32 (on MS-DOS). - Add support for AmigaOS. - Rename `Makefile.m32` to `Makefile.mk` - Replace `ARCH` with `TRIPLET`. - Build `tool_hugehelp.c` proper (when tools are available). - Drop MS-DOS compatibility macro `USE_ZLIB` (replaced by `HAVE_LIBZ`) - Add support for `ZLIB_LIBS` to override `-lz`. - Omit object files when building examples. - Default `CC` to `gcc` once again, for convenience. (Caveat: compiler name `cc` cannot be set now.) - Set `-DCURL_NO_OLDIES` for examples, like autotools does. - Delete `makefile.dj` files. Notice the configuration details and defaults are not retained with the new method. - Delete `makefile.amiga` files. A successful build needs a few custom options. We're also not retaining all build details from the existing Amiga make files. - Rename `Makefile.m32` to `Makefile.mk` to reflect that they are not Windows/MinGW32-specific anymore. - Add support for new `CFG` options: `-map`, `-debug`, `-trackmem` - Set `-DNDEBUG` by default. - Allow using `-DOS=...` in all `lib/config-*.h` headers, syncing this with `config-win32.h`. - Look for zlib parts in `ZLIB_PATH/include` and `ZLIB_PATH/lib` instead of bare `ZLIB_PATH`. Note that existing build configurations for MS-DOS and AmigaOS likely become incompatible with this change. Example AmigaOS configuration: ``` export CROSSPREFIX=/opt/amiga/bin/m68k-amigaos- export CC=gcc export CPPFLAGS='-DHAVE_PROTO_BSDSOCKET_H' export CFLAGS='-mcrt=clib2' export LDFLAGS="${CFLAGS}" export LIBS='-lnet -lm' make -C lib -f Makefile.mk make -C src -f Makefile.mk ``` Example MS-DOS configuration: ``` export CROSSPREFIX=/opt/djgpp/bin/i586-pc-msdosdjgpp- export WATT_PATH=/opt/djgpp/net/watt export ZLIB_PATH=/opt/djgpp export OPENSSL_PATH=/opt/djgpp export OPENSSL_LIBS='-lssl -lcrypt' export CFG=-zlib-ssl make -C lib -f Makefile.mk make -C src -f Makefile.mk ``` Closes #9764
* tidy-up: delete parallel/unused feature flagsViktor Szakats2022-10-061-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Detecting headers and lib separately makes sense when headers come in variations or with extra ones, but this wasn't the case here. These were duplicate/parallel macros that we had to keep in sync with each other for a working build. This patch leaves a single macro for each of these dependencies: - Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`. Also delete CMake logic making sure these two were in sync, along with a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`. Also delete stray `HAVE_ZLIB` defines. There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch retains it for compatibility and deprecates it. - Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`. Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from `winbuild/MakefileBuild.vc`, these have a role when building libssh2 itself. And `CURL_USE_LIBSSH`, which had no use at all. Also delete stray `HAVE_LIBSSH2` defines. - Rely on `USE_LIBSSH`, delete parallel `HAVE_LIBSSH_LIBSSH_H`. Also delete `LIBSSH_WIN32`, `LIBSSH_LIBRARY` and `HAVE_LIBSSH` from `winbuild/MakefileBuild.vc`, these were the result of copy-pasting the libssh2 line, and were not having any use. - Delete unused `HAVE_LIBPSL_H` and `HAVE_LIBPSL`.

* functypes: provide the recv and send arg and return typesDaniel Stenberg2022-09-281-4/+0
| | | | | | | | | | | | This header is for providing the argument types for recv() and send() when built to not use a dedicated config-[platfor].h file. Remove the slow brute-force checks from configure and cmake. This change also removes the use of the types for select, as they were not used in code. Closes #9592

[2] Related comment can possibly be deleted in `packages/vms/generate_config_vms_h_curl.com`. [3] There are more instances of this in autotools, but I did not dare to touch those. Looked like it's used to detect socket support. [4] This is necessary for MFC (Microsoft Foundation Class) DLLs to force linking MFC components statically to the DLL. `libcurl.dll` does not use MFC, so we can delete this define.
