problems w/ .config for getting ctypes for shell compiled #29

1st: thanx very much or this amazing ideas to have shells executing c-like commands due out of this incredible feature I am trying actually to get the sources compiled on OSX for using those extension in bash. I want use ctypes in OSX bash installed w/ brew in version: | => bash -version GNU bash, version 4.3.42(1)-release (x86_64-apple-darwin14.5.0) Copyright (C) 2013 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later http://gnu.org/licenses/gpl.html When I do .config the following error on terminal appears:

configure: error: in /Users/RogiWanKenobi/ctypes.sh': configure: error: unable to build a test extension Seeconfig.log' for more details

And the mentioned log file shows: conftest.c:11:10: fatal error: 'ac_nonexistent.h' file not found

include 

     ^

1 error generated. configure:7590: $? = 1 configure: failed program was: | /* confdefs.h */

So, how do I get the sources for ctypes.sh compiled correctly?

Any hint is highly appreciated.

Thanks in advance, Roger

Hi Roger, I'm not sure it will work on OSX because of the way Apple compile bash. IIRC, they don't export dynamic symbols - this is a common mistake, because not many people use bash plugins, so the bug doesn't get noticed.

What does it mean tome that this bug does not get noticed? On your hint I was investigating my issue: Since I am working with a brew env on osx I checked using the following nly in my brew env:

So what I found in the configure log was the following: configure:7517: $? = 0 configure:7531: gcc -E conftest.c conftest.c:11:10: fatal error: 'ac_nonexistent.h' file not found

include 

     ^

1 error generated. configure:7531: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "ctypes.sh"

So, to me it seems there is a kind of '.h' file missing.

What do you think?

Regards, Roger

Sorry, I touched the wrong button; in my eyes it is not to be seen as closed.

So, reopened it.

I think there is not much we can do about this until Apple fix their bash build. I verified on an El Capitan installation that no symbols are available, which means you can load a plugin but you can't do anything useful with it.
