Errors compiling beta

[Karl Garrison]

Since I couldn't get the RPM to work on RedHat 7.1 (see my other post), I thought I would see if I would have more luck compiling from source. I ried, but it errors out. Here are the errors I get. Any ideas?


Thanks,

This shouldn't happen. I believe you have a fouled up installation of G++. I notice you're using gcc 3.0: did you install it yourself ?
Are you building with RPM ?

rpm --rebuild exult-0.96beta1-1.src.rpm

[Karl]

What makes you think I'm using gcc 3.0? I don't think I have that installed, but I'll check to make sure when I get home. I should have gcc 2.96, the RedHat fork of gcc that comes with RedHat 7.x.

I also tried rebuilding the source RPM with similar results, so I tried compiling with the tarball source when that failed. Maybe I'll check to see if autoconfig is somehow detecting the wrong compiler when I get home . Thanks for your help.

I had the same problem once when I tried to compile exult with gcc3. It won't work (at least for me, it didn't).
gcc3 compiled c++ programs are terribly slow anyway so don't use it (yet

--Darkstar

[Karlos]

Okay, I checked at home, and I definately have gcc 2.96 installed, not 3.0. The directory /usr/include/g++-3/ seen in the error posted above definately comes from the gcc-2.96 package (I checked with rpm).

Obviously it's something particular with my system, since I was able to get the RPM to work on a stock RedHat 7.1 machine at work, and was also able to recompile from work, but neither works on my machine at home. I'm not sure how to troubleshoot this, however.

Another thought: maybe I can try recompiling with egcs (a.k.a. kgcc) instead of gcc-2.96. Does anyone know how to tell ./configure to use a different compiler? Just setting CC=kgcc didn't seem to be enough to do the trick.


-Karl

[nadir]

kgcc only comes with a C (not C++) frontend. Therefore that won't work.
Also you'd have to set CXX=kg++ (or equivalent).
What release of gcc 2.96 are you running ?
Make sure you're using the latest packages from RedHat

gcc-2.96-85.i386.rpm
gcc-c++-2.96-85.i386.rpm
libstdc++-2.96-85.i386.rpm
libstdc++-devel-2.96-85.i386.rpm
cpp-2.96-85.i386.rpm

A pity Microsoft compiler (which never problems with C++ since early 90ies) cannot build ELF binaries and Linux cannot load PE ones.
Maybe some smartie will add PE binary format support to the kernel and to ld.so?

[wjp]

It's not just the exe format that's different, you know

Anyway, if you want to run windows executables in linux, try wine. (www.winehq.org)

[Max aka Moscow Dragon]

>It's not just the exe format that's different, you know

I mean:
- having a Linux binary
- linked over a Linux libc.so and X toolkits
- using no Win32 functions, only Linux ones
- but with PE format!

MS compiler (not like Borland C++ Builder) can happily produce this if you will customize the entry point code.

Does WINE support COM/OLE?

[nadir]

Wine supports COM/OLE.
G++ >=3.x (including 2.96 which is a pre 3.0 release) is more conformant to ISO C++ than Microsoft's compiler. The problems Karl is having are because of a screwed up installation.
The only aspect of MSVC that is superior to GCC is that it supports precompiled headers (they are coming in GCC 3.1).
I believe the best C++ compiler out there at the moment is Metrowerks C++ (Fingolfin ?).

But no compiler can compete with GCC in terms of supported frontends and backends:
Currently the main GCC distribution contains front ends for C (gcc), C++ (g++), Objective C, Chill (unmaintained), Fortran (g77), Java (GCJ), and Ada (GNAT). GCC 3.1 will be the first official version of GCC to include the Ada front end.

The very impressive list of supported architectures is here
