libgeotiff lesson for today

31 Jul 2008 | mloskot

Doing final tests of libLAS on Linux (Ubuntu 7.04), before Hobu will release 1.0.0, I attempted to build it with latest libgeotiff 1.2.5. I moved my fingers on keyboard and did ./configure && make, shortly then I saw strange looking error message:

/usr/bin/ld: makegeo: hidden symbol `__stack_chk_fail_local' in /usr/lib/libc_nonshared.a(stack_chk_fail_local.oS) is referenced by DSO
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status

Google is your friend, so in a few seconds I knew what’s going wrong. ./configure sets Makefile to call ld -shared. However, it does not work with GCC 4, because ld linker does not include all required references to other shared libraries. Simply, GCC linker driver seems to handle shared references better, than bare ld.

The conclusion is, that if you use GCC 4.x and you want to build libgeotiff, configure it this way:

./configure --with-ld-shared="gcc -shared"

Update July 31, 2008: Another solution is to add -fno-stack-protector option to CFLAGS and CXXFLAGS. Regarding Ubuntu Linux, this issue seems to be related to enabled SSP support (see also Ubuntu Wiki) available in GCC 4.1.
