Hi all.

I'm running into an error when running ./configure (I can post the file if that helps) and getting the entertaining message:
checking for g++... g++
checking whether the C++ compiler (g++ -s) works... no
configure: error: installation or configuration problem: C++ compiler cannot create executables.

Do any of you have suggestions on what steps to take from here? I'm new to OSX, and have only limited development experience on Linux, so don't be afraid to get pedantic (I'd search the darwin lists, but Apple hasn't made them searchable yet, and I haven't found this in any other searches)

I copied the config.guess and .sub files over from /usr/libexec/, and have symlinked /usr/bin/cc to /usr/bin/gcc, and /usr/bin/c++ to /usr/bin/g++.

Finally, the config.log ends with the following:

configure:1180: checking how to run the C preprocessor
configure:1201: gcc -E conftest.c >/dev/null 2>conftest.out
configure:1197: undefined type, found `Syntax'

e must contain at least global symbols, for maximum stripping use -x)
configure: failed program was:

#line 1375 "configure"
#include "confdefs.h"

int main(){return(0);}


Just so you know, the software I'm trying to compile is a really impressive 3d skeleton animation program (http://prdownloads.sourceforge.net/cal3d/cal3d-0.5.tar.gz).

Here's the blurb from the developer's home page (www.beosil.com)
<blockquote>Cal3d is a skeletal based 3d character animation library written in C++ in a platform-/graphic API-independent way. Originally designed to be used in a 3d client for Worldforge, it evolved into a stand-alone product which can be used in many different kinds of projects.</blockquote>


Sincere thanks for your time,

Look at line 1380 in configure and try removing the -s parameter.

Wade,

Thanks for the suggestion. I tried picking my way through the configure file, and might have successfully excised the -s flag for that test, but I didn't get things working. Configure files are notoriously opaque. I've set up an account for the developer to try poking around (OT: It is wonderful to be able to ssh to my mac and set up an account for another user to try building UNIX software. I don't know when I'll get over that pleasure).

I'll try to post a solution if I find one so others with the same problem might find help.

Thanks,

anubis

It turns out there was a line setting LDFLAGS="-s" that was the culprit. With that removed, we could get on to other errors related to the portability of the code. Look for a MacOSX friendly version of Cal3d soon.

I am having a problem. I get this when I configure:

onfiguring for powerpc-apple-machten
checking for gcc... gcc
checking for g++... no
checking for ld... ld
checking for ar... ar
checking for ranlib... ranlib
checking for gcc... (cached) gcc
checking whether the C compiler (gcc -traditional-cpp ) works... yes
checking whether the C compiler (gcc -traditional-cpp ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether gcc accepts -g... yes
checking for c++... :
checking whether the C++ compiler (: ) works... no
configure: error: installation or configuration problem: C++ compiler cannot create executables.

I checked -s flags and ld-s but found none..any ideas?

A couple of things. You want to be building for powerpc-apple-darwin1.3 not powerpc-apple-machten. If you copy the config.sub and config.guess from /usr/libexec over the ones in your prject it should help.

The default makefiles that come with OS X attempt to make fat (PPC i386) binaries of everything, but the compiler that comes with dev tools only outputs PPC, causing this to fail. Try editting the RC_ARCHS line in /Developer/Makefiles/CoreOS/ReleaseControl/Common.make

Louis, AFAIK the config.sub and config.guess were moved to /usr/share/libtool. Am I mistaken? They used to be in /usr/libexec but I think they were moved for GM release.

I could believe that, but they are in /usr/libexec on my system. Then again, my system has some... oddities.

Nope, they're still in /usr/libexec.
