Bug#818715: ros-image-common: FTBFS on several architectures: relocation R_X86_64_PC32 against symbol `_ZTVN7testing8internal17TestEventRepeaterE' can not be used when making a shared object; recompile with -fPIC

[Emilio Pozuelo Monfort]

Source: ros-image-common
Version: 1.11.10-4
Severity: serious

Your package failed to build on several architectures:

/usr/bin/ld: CMakeFiles/gtest.dir/src/gtest-all.cc.o: relocation R_X86_64_PC32 against symbol `_ZTVN7testing8internal17TestEventRepeaterE' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status

It looks as if that file was compiled with -fPIC though:

cd /«PKGBUILDDIR»/obj-x86_64-linux-gnu/gtest && /usr/bin/c++   -DGTEST_CREATE_SHARED_LIBRARY=1 -Dgtest_EXPORTS -I/usr/src/gtest/include -I/usr/src/gtest  -g -O2 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2  -fPIC   -g -O2 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2  -Wall -Wshadow -DGTEST_HAS_PTHREAD=1 -fexceptions -Wextra -Wno-unused-parameter -Wno-missing-field-initializers -o CMakeFiles/gtest.dir/src/gtest-all.cc.o -c /usr/src/gtest/src/gtest-all.cc

On ppc64el the error is a bit different, but it also points to -fPIC so the
problem is likely the same:

/usr/bin/c++  -fPIC -g -O2 -fPIE -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2   -fPIE -pie -Wl,-z,relro -Wl,-z,now -shared -Wl,-soname,libgtest.so -o libgtest.so CMakeFiles/gtest.dir/src/gtest-all.cc.o  -L/«PKGBUILDDIR»/obj-powerpc64le-linux-gnu/gtest/src -lpthread -Wl,-rpath,/«PKGBUILDDIR»/obj-powerpc64le-linux-gnu/gtest/src
