How can I set ccshared=-fPIC while executing ./configure?

Question

I am trying to build Python 2.6 for QGIS on RHEL 5. During the making of QGIS I get the following error:

Linking CXX shared library libqgispython.so
/usr/bin/ld:         


        

Answer 1

The following worked for me when I ran into this error:

make clean
./configure CFLAGS=-fPIC CXXFLAGS=-fPIC

Answer 2

I got it working with:

./configure --enable-shared --enable-pic

Answer 3

1. Run ./configure --help, possibly piping to grep PIC, to see if there's an option to enable this
2. Try setting the environment variable before running configure, e.g. CCSHARED="-fPIC" ./configure (as a single command, assuming bash)

If neither of those work, you need to read the configure code and understand the conditions it tests for better.

Answer 4

The following has an example of passing fPIC to configure

Answer 5

I got it working by adding -fPIC after CC= gcc -pthread, i.e CC= gcc -pthread -fPIC in the Makefile.

Answer 6

Run configure with --enable-shared. Then -fPIC will be included as part of the shared flags.
