[100/200/300/400] GCC, the GNU Compiler Collection

[vaidyasr]

The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages (libstdc++, libgcj,...). GCC was originally written as the compiler for the GNU operating system. The GNU system was developed to be 100% free software, free in the sense that it respects the user's freedom.

Installation:
For 100 Series : O-PKG.
For 200/300 Series : O-PKG.
For 400 Series : O-PKG.

Included compilers: gcc, g++

Installed under /share/Apps/local

Instructions:
To compile any program in 200 series, set the following variable.

Code:

# export CC="gcc -EL -fPIC -march=74kc"
# export CXX="g++ -EL -fPIC -march=74kc"
# export CFLAGS="-I/usr/local/include -EL -fPIC -march=74kc"
# export CXXFLAGS="-I/usr/local/include -EL -fPIC -march=74kc"
# export LDFLAGS="-L/usr/local/lib -L/opt/syb/sigma/lib -L/opt/syb/app/lib -EL -fPIC -march=74kc"

For 100 series, the compiler is here. You can test it and report the issues.

well done Vaidyasr,

A1?0 port coming ?

So this means the floodgates will open on other packages that have non-existent or problematic cross-compile scripts.

avimerge(transcode) please anyone

avimerge already available in c200. You want them in A1XX?

[dc11ab]

Looking forward to try this out!
I hope the compiling process doesn't take too long.

I look forward to it also but don't expect short compile times.

I can only guess how long it would take to re-compile GCC on the actual C/A-200. It would not be nice. Still, many small apps will compile in a fairly short time. Maybe an hour or maybe over night? It is a great step. I need to compile my "joe" editor. Haven't seen it done so far.

[dc11ab]

I've done some native compiling on my NAS (mips 500 MHz, 128 MB RAM) and I think llink took more than one hour, perhaps nearly two to complete - still that's a fairly light package. Smaller utilities only takes about 20 minutes or so, depending upon passes etc.

[vaidyasr]

The compiler package is ready. If someone is ready to test before releasing via CSI, the package is available via http://c200utils.googlecode.com/files/local.zip

Create a directory /share/Apps/local and extract the zip/tar contents under the above directory. If required, set the LD_LIBRARY_PATH for compiling. The package doesn't included a make binary. So, you can try a small C program which don't require make.

---

Tested in my C200. It seems I need to include the header files for compiling. Repackging again.

[nuke12]

Compiling make would be a good test.

GNU Make can be found here;
http://ftp.gnu.org/gnu/make/

I think it is as simple as;

./configure
and because there is no "make" yet, you have to;
./sh build.sh

Oh, and cross your fingers.

---

WinRar is giving me errors on your file.

When it first opens it, I get;
Unexpected end of archive

And when I try to open the ".tar" within, I get;
The archive is either in unknown format or damaged

Oops....must have been the download. I tried it a second and third time and it was ok.

[vaidyasr]

Ok, when compiling the make, I get the below error. I need to look into the ld binary.

Code:

configure:3166: $? = 1
configure:3186: checking whether the C compiler works
configure:3208: gcc    conftest.c  >&5
/share/Apps/local/bin/ld: this linker was not configured to use sysroots
collect2: ld returned 1 exit status

[nuke12]

Oops, I tried yesterday morning and then got side tracked. I ment to comment then. Anyway, I'm getting the same error when I try to ./configure make.

[nuke12]

Oh, another comment here for anyone else playing with this. You can use WinZip or WinRar to extract the .tar file from the .zip but don't use WinRar to take apart the .tar. It will generate linkage errors. Use tar on the PCH to extract eg. "tar -xvf local.tar".

[nuke12]

vaidyasr;

Did you find the issue with ld?

No, I'll do it tomorrow.

[vaidyasr]

The compiler in C200 is working PERFECT. I was able to compile a simple program a2cnfo.c in C200 within 10 seconds.

So will make compile now?
