When compiling GDAL with python support, under certain build chain environment variables, next error may appear when building and linking python extensions (https://www.mail-archive.com/freebsd-ports@freebsd.org/msg41030.html):

/bin/sh: -d: invalid option

See the Github PR for proposed solution.

Please describe the problem and your proposed solution in more detail and in terms of CPython, so that it can be discussed by the relevant experts.  GDAL is a third party product and only relevant as an example, so it would also be good to come up with a better title for the issues ;)

When compiling GDAL with python support, before Lib/distutils/unixccompiler.py:180,

self.compiler_cxx = ['/bin/sh', '/usr/x86_64-pc-linux-gnu/bin/libtool', '--mode=compile', '--tag=CXX', 'x86_64-pc-linux-gnu-c++']
linker = ['x86_64-pc-linux-gnu-cc', '-pthread', '-shared', '-march=native', '-pipe', '-O2', '-Wall', '-Wdeclaration-after-statement', '-Wextra', '-Winit-self', '-Wunused-parameter', '-Wmissing-prototypes', '-Wmissing-declarations', '-Wformat', '-Werror=format-security', '-Wno-format-nonliteral', '-Wlogical-op', '-Wshadow', '-Werror=vla', '-Wdeclaration-after-statement', '-Wnull-dereference', '-Wduplicated-cond', '-DOGR_ENABLED', '-march=native', '-pipe', '-O2', '-I/var/tmp/paludis/build/sci-libs-gdal-2.1.1/work/gdal-2.1.1/port', '-DGDAL_COMPILATION']

and after the workaround code:

linker = ['/bin/sh', '-pthread', '-shared', '-march=native', '-pipe', '-O2', '-Wall', '-Wdeclaration-after-statement', '-Wextra', '-Winit-self', '-Wunused-parameter', '-Wmissing-prototypes', '-Wmissing-declarations', '-Wformat', '-Werror=format-security', '-Wno-format-nonliteral', '-Wlogical-op', '-Wshadow', '-Werror=vla', '-Wdeclaration-after-statement', '-Wnull-dereference', '-Wduplicated-cond', '-DOGR_ENABLED', '-march=native', '-pipe', '-O2', '-I/var/tmp/paludis/build/sci-libs-gdal-2.1.1/work/gdal-2.1.1/port', '-DGDAL_COMPILATION']

which leads to next error:

/bin/sh: -d: invalid option

Some fixes to compilation (https://www.michael-joost.de/gdal_install.html) have been found, but anyway the existing workaround:

1. ...is a hack about OSX but there is no platform checking,

2. ...assumes linker and compiler commands have similar structure and
environment settings (no documentation reference found about that), and

3. ...assumes `env`, if used, does not come with any modifier.

My proposal is to remove the workaround and delegate right environmental variables to packagers.

I doubt we can make the change this way for backward compatibility reasons.  That doesn't mean the situation can't be improved, though.

As I mentioned on the pull request it is not clear to me what the actual issue is.

What are the settings for building that cause problems?  In particular, what are the compiler/linker related variables in Python's Makefile (and _sysconfigdata.py)?

With the currently available information I'm -1 w.r.t accepting the attached pull request.

I'm going to close this as the OP hasn't responded in over 2 years and Ronald was -1 on the solution.  If the OP or someone else experiences this same problem, either this issue or a new one can be opened to address it.  Thank you!
