Hi! I, as Fedora's vim co-maintainer, encountered the issue with default LDFLAGS. I tried to manually run configure script for Vim, with ruby support enabled, but it always failed with error message about missing ncurses (ncurses-devel was installed though). When I looked into config.log, I saw: configure:12069: gcc -o conftest -g -O2 -L. -Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -fstack-protector -rdynamic -Wl,-export-dynamic -L/usr/local/lib conftest.c -lselinux -lncurses >&5 conftest.c: In function 'main': conftest.c:67:26: warning: implicit declaration of function 'tgetent' [-Wimplicit-function-declaration] char s[10000]; int res = tgetent(s, "thisterminaldoesnotexist"); ^~~~~~~ /usr/bin/ld: /tmp/ccivPtT5.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIC /usr/bin/ld: final link failed: nonrepresentable section on output collect2: error: ld returned 1 exit status Adding -fPIC actually solved it, but why does the script want it in the first place? Then I ran configure without ruby support enabled and it passed... again from config.log I found out that script wants ruby's LDFLAGS, because script needs them for compilation of ruby support and Ruby LDFLAGS are: -L. -Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -fstack-protector -rdynamic -Wl,-export-dynamic , where '-specs=/usr/lib/rpm/redhat/redhat-hardened-ld' causes the issue. I talked with Vita Ondruch, Fedora's ruby maintainer, and he explained Ruby embeds LDFLAGS from the machine, where Ruby was built - in our case in our building system, and Ruby's upstream are not willing to change this behavior. To sum it up, I would like to ask if there is way how to solve it in our build system, not in Vim or Ruby projects themselves - because at least Ubuntu does not have this issue... and python+perl seem to have it solved too. (I can patch Vim downstream in the worst scenario...) Thank you for reading the email and answers in advance! Zdenek -- Zdenek Dohnal Associate Software Engineer Red Hat Czech - Brno TPB-C
