Problem Compiling with Gcc

[ummd]

I'm trying to compile Gambit, an open source game theory project and I'm receiveing the following error.
Any ideas on what this -lcrt1.o is? I admit inexperience in this sort of thing, but I have installed Apple's gcc compiler (Custom install of Developer Tools software and gcc 4).

Thanks in advance

gcc version 4.0.1 (Apple Computer, Inc. build 5367)
configure:2279: $? = 0
configure:2302: checking for C compiler default output file name
configure:2305: gcc conftest.c >&5

I strongly suspect that the "custom" install is what is causing the problem. Unless you are an expert, you want to use the default install for Xcode - or at least only add things to the install, not remove things.

The file that is missing is the C run-time library.

Hi,

MacOSX does not seem to support true static linking.
I think -lcrt1.o is a missing part of object code which would allow the binary to be linked against a libc.a. Here the c code is just fine, but in the config script you might have chosen a default or option like ...

--link-static


Try something like

--link-dynamic

or

--link-static=no

typically "configure --help" will give a good overview about basic config options.

Best of luck, I think you'll take it from here alone.

Cheers,
Michael
