From 5ff06d762a88077aff0fb637c931c64e6f47f93d Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Mon, 6 Apr 2020 23:32:44 +0100 Subject: libatomic/test: Fix compilation for build sysroot Fix a problem with the libatomic testsuite using a method to determine the compiler to use resulting in the tool being different from one the library has been built with, and causing a catastrophic failure from the lack of a suitable `--sysroot=' option where the `--with-build-sysroot=' configuration option has been used to build the compiler resulting in the inability to link executables. Address this problem by providing a DejaGNU configuration file defining the compiler to use, via the GCC_UNDER_TEST TCL variable, set from $CC by autoconf, which will have all the required options set for the target compiler to build executables in the environment configured, removing failures like: .../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory .../bin/riscv64-linux-gnu-ld: cannot find -lm collect2: error: ld returned 1 exit status compiler exited with status 1 FAIL: libatomic.c/atomic-compare-exchange-1.c (test for excess errors) Excess errors: .../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory .../bin/riscv64-linux-gnu-ld: cannot find -lm UNRESOLVED: libatomic.c/atomic-compare-exchange-1.c compilation failed to produce executable and bringing overall test results for the `riscv64-linux-gnu' target (here with the `x86_64-linux-gnu' host and RISC-V QEMU in the Linux user emulation mode as the target board) from: === libatomic Summary === # of unexpected failures 27 # of unresolved testcases 27 to: === libatomic Summary === # of expected passes 54 libatomic/ * configure.ac: Add testsuite/libatomic-site-extra.exp to output files. * configure: Regenerate. * libatomic/testsuite/libatomic-site-extra.exp.in: New file. * testsuite/Makefile.am (EXTRA_DEJAGNU_SITE_CONFIG): New variable. * testsuite/Makefile.in: Regenerate. --- libatomic/configure.ac | 1 + 1 file changed, 1 insertion(+) (limited to 'libatomic/configure.ac') diff --git a/libatomic/configure.ac b/libatomic/configure.ac index b8df11b4bf3..7ac8911c342 100644 --- a/libatomic/configure.ac +++ b/libatomic/configure.ac @@ -288,4 +288,5 @@ else fi AC_CONFIG_FILES(Makefile testsuite/Makefile) +AC_CONFIG_FILES(testsuite/libatomic-site-extra.exp) AC_OUTPUT -- cgit v1.2.1
