Compiling xidel using cross compiler for mips platform ? #36

Closed Baltazar500 closed 4 years ago

Baltazar500 commented 5 years ago

Hello.

How to compile the xidel binary for the mips platform using this cross-compiler http://www.codesourcery.com/sgpp/lite/mips/portal/package4432/public/mips-linux-gnu/mips-4.3-154-mips- linux-gnu-i686-pc-linux-gnu.tar.bz2 ? I use debian and I need to build a binary file for the Dune HD media player, which is based on mips. Simple build examples using gcc or make do not cause problems, but xidel uses FreePascal and I don’t know how to build a binary :(

Need to install free pascal? Package "fpc" ? And use build.sh with command line switches ? What are the command line switches ?

Sorry, I'm newbie

You need a freepascal cross compiler. Since there is probably no package for that you need to compile freepascal first. Get it with svn clone https://svn.freepascal.org/svn/fpc/trunk

It can be compiled with something like sudo make crossinstall OS_TARGET=linux CPU_TARGET=mips. Or CPU_TARGET=mipsel for little endian

It likely needs ld, as and crt* from the package you have linked. It searchs for files like mips-linux-as and mips-linux-ld, so the easiest way is to copy them to the $PATH and rename them. You can configure the path to crt in ~/.fpc.cfg, like:

 #IFDEF mips
 -Fl/...basepath.../lib/gcc/mips-linux-gnu/4.3.3
 #endif

And use build.sh with command line switches ? What are the command line switches ?

fpc's compiler is actually called ppc*. The cross compiler probably something like ppcmips, so you need to call it with build.sh --compiler ppcmips. Then it uses the cross compiler. You might need to set -Pmips to set the target cpu, otherwise it might try to use the cross compiler to create a x86 xidel version, but the script has no option for that, then you need to put -Pmips in the script code

For me, building xidel using free pascal turned out to be impossible :(

I do not have enough experience and knowledge to compile.

Is it possible in the future that xidel will be built for mips from you?

dont have anything useful to contribute to the discussion :) im just curious about the machine you intend to run it on, if you can share a link

Greetings. Sorry for bad English and ugly code.

In attachment - script for crossbuilding xidel from Debian 10 (Buster) x86 to mipsel-linux. build_xidel_mipsel.txt

Patch for synapse/ssfpc.inc based on lines 32-39 of socketsh.inc from FPC source - https://svn.freepascal.org/svn/fpc/trunk/packages/rtl-extra/src/inc/socketsh.inc

Best Regards, Alexey.

That is a good description, so if someone needs mips they can follow those instructions.
