Source: xtensor Followup-For: Bug #995867 Control: retitle -1 mipsel FTBFS (relocation truncated to fit: R_MIPS_CALL16)
The problem with undefined `__umodsi3' `__udivsi3' is not easily reproduced. But the mipsel build failure is consistent. The more common symptom is "relocation truncated" errors e.g. [ 39%] Linking CXX executable test_xreducer cd /<<PKGBUILDDIR>>/obj-mipsel-linux-gnu/test && /usr/bin/cmake -E cmake_link_script CMakeFiles/test_xreducer.dir/link.txt --verbose=1 /usr/bin/c++ -O0 -std=c++14 -Wunused-parameter -Wextra -Wreorder -Wconversion -Wsign-conversion -Wold-style-cast -Wunused-variable -ftemplate-backtrace-limit=0 -Wl,-z,relro -rdynamic CMakeFiles/test_xreducer.dir/main.cpp.o CMakeFiles/test_xreducer.dir/test_xreducer.cpp.o -o test_xreducer -lpthread cd /<<PKGBUILDDIR>>/obj-mipsel-linux-gnu/test && /usr/bin/c++ -I/<<PKGBUILDDIR>>/include -O0 -std=c++14 -Wunused-parameter -Wextra -Wreorder -Wconversion -Wsign-conversion -Wold-style-cast -Wunused-variable -ftemplate-backtrace-limit=0 -MD -MT test/CMakeFiles/test_xexpression_traits.dir/main.cpp.o -MF CMakeFiles/test_xexpression_traits.dir/main.cpp.o.d -o CMakeFiles/test_xexpression_traits.dir/main.cpp.o -c /<<PKGBUILDDIR>>/test/main.cpp CMakeFiles/test_xreducer.dir/test_xreducer.cpp.o: in function `__gthread_active_p()': test_xreducer.cpp:(.text+0x1c): relocation truncated to fit: R_MIPS_GOT16 against `__pthread_key_create@@GLIBC_2.0' CMakeFiles/test_xreducer.dir/test_xreducer.cpp.o: in function `xt::xreducer_features::xreducer_features()': test_xreducer.cpp:(.text+0x23c): relocation truncated to fit: R_MIPS_CALL16 against `_Unwind_Resume@@GCC_3.0' test_xreducer.cpp:(.text+0x2ac): relocation truncated to fit: R_MIPS_CALL16 against `_Unwind_Resume@@GCC_3.0' CMakeFiles/test_xreducer.dir/test_xreducer.cpp.o: in function `xt::_DOCTEST_ANON_FUNC_2()': test_xreducer.cpp:(.text+0x418): relocation truncated to fit: R_MIPS_CALL16 against `raise@@GLIBC_2.0' test_xreducer.cpp:(.text+0x4b0): relocation truncated to fit: R_MIPS_CALL16 against `__cxa_begin_catch@@CXXABI_1.3' test_xreducer.cpp:(.text+0x4e0): relocation truncated to fit: R_MIPS_CALL16 against `__cxa_end_catch@@CXXABI_1.3' test_xreducer.cpp:(.text+0x504): relocation truncated to fit: R_MIPS_CALL16 against `__cxa_end_catch@@CXXABI_1.3' test_xreducer.cpp:(.text+0x5a4): relocation truncated to fit: R_MIPS_CALL16 against `_Unwind_Resume@@GCC_3.0' CMakeFiles/test_xreducer.dir/test_xreducer.cpp.o: in function `xt::_DOCTEST_ANON_FUNC_4()': test_xreducer.cpp:(.text+0x70c): relocation truncated to fit: R_MIPS_CALL16 against `raise@@GLIBC_2.0' test_xreducer.cpp:(.text+0x7a4): relocation truncated to fit: R_MIPS_CALL16 against `__cxa_begin_catch@@CXXABI_1.3' test_xreducer.cpp:(.text+0x7d4): additional relocation overflows omitted from the output collect2: error: ld returned 1 exit status make[3]: *** [test/CMakeFiles/test_xreducer.dir/build.make:116: test/test_xreducer] Error 1 "relocation truncated" together with the virtual memory exhaustion seen without -O0 suggests the test program is simply too large to link. But the problem persists even if XTENSOR_TESTS in tests/CMakeLists.txt is reduced to one file.
