Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to the maintainer. *** Error code 1 Stop. make[1]: stopped in /usr/ports/devel/gdb *** Error code 1 Stop. Upon further inspection to config.log, I found the following interesting nugget: configure:7953: checking whether to use python configure:7955: result: /usr/local/bin/python2.7 configure:8173: checking for python2.7 configure:8191: cc -o conftest -pipe -DRL_NO_COMPAT -g -g -std=gnu89 -I/usr/local/include/python2.7 -I/usr/local/include/python2.7 conftest.c -lncurses -lz -lm -L/usr/local/lib/python2.7/config -lintl -lutil -lm -lpython2.7 -Wl,--export-dynamic >&5 /usr/bin/ld: cannot find -lintl cc: error: linker command failed with exit code 1 (use -v to see invocation) >How-To-Repeat: # cd /usr/ports/devel/gdb # make config -> Select [*] PYTHON # make >Fix: Attached is a very, very crude patch that just blindly adds /usr/local/lib to gdb's python-config.py script, which does allow it to compile correctly. Something more elegant is almost assuredly needed, but I'm not sure the best way to go about this. Patch attached with submission follows: *** gdb-7.6/gdb/python/python-config.old Sat Sep 21 11:33:51 2013 --- gdb-7.6/gdb/python/python-config.py Sat Sep 21 11:34:05 2013 *************** *** 72,77 **** --- 72,78 ---- libs.insert(0, '-L' + getvar('LIBPL')) elif os.name == 'nt': libs.insert(0, '-L' + sysconfig.PREFIX + '/libs') + libs.insert(0, '-L/usr/local/lib') if getvar('LINKFORSHARED') is not None: libs.extend(getvar('LINKFORSHARED').split()) print (to_unix_path(' '.join(libs))) >Release-Note: >Audit-Trail: >Unformatted:
