In the last post I showed you that vamos is already able to call the SAS C Compiler 6.58 and compile some example source files. In the last few days I added the missing parts to vamos to support smake, too. Namely, calling sub processes with SystemTagList() was added and lots of bugs fixed. With smake at hand I am able to compile some real SAS C projects with an smakefile describing the build.
1. Setup Build Environment
- I assume that you have installed the SAS C compiler ready to use for vamos as described in my last post
- The netword driver we will compile needs the Amiga Network Driver Includes (i.e. SANA-II headers)
> cd ~/amiga/src > lha x ~/Downloads/AmiTCP-SDK-4.3.lha
- Now we need to setup assigns in vamos so the build can reach the new network includes. My ~/.vamosrc config file looks like this:
[volumes] wb310=~/amiga/wb310 sc=~/amiga/shared/sc net=~/amiga/src/AmiTCP-SDK-4.3 [assigns] include=sc:include lib=sc:lib t=root:tmp c=wb310:c netinclude=net:netinclude netlib=net:netlib includeasm=sc:include [path] path=sc:c,wb310:c [vamos] quiet=True ram_size=2048
What’s new here?
- First I added a new volume in vamos called net: where the SANA-II includes reside. It points to the native path we just unpacked.
- Some new assigns were added: netinclude and netlib point inside our new net: volume
- Another assign called includeasm: was necessary as the following build requires it. It simply points directly to the include directory in the SAS C installation.
- Finally, a new section called vamos was introduced. This section holds defaults for common option that were currently only available via command line:
- The quiet switch is similar to the -q command line option and suppresses information about un-implemented Amiga OS calls in vamos
- The ram_size sets the RAM for the AmigaOS emulation of vamos to 2 MiB. Similar to the -m command line option. This ensures that we do not run out of memory during compilation.
2. Grab the Source
- Next we download the source for magPLIP from aminet
- I unpacked the source in a build directory:
> mkdir ~/build > cd build > lha x ~/magPLIP38.1.lha > ls magplip/ magplip.info
- I also downloaded the plip2slip-0.1 source archive because it contains a patch for the driver we are going to build
- Unpack this, too:
> unzip ~/Downloads/plip2slip-0.1.zip > ls magplip/ magplip.info plip2slip-0.1/
- Next, we patch the source:
> patch -p0 < plip2slip-0.1/contrib/magplip/magplip.patch patching file magplip/source/magplip_rev.h patching file magplip/source/magplip_rev.i patching file magplip/source/magport.asm patching file magplip/source/server.c patching file magplip/source/smakefile
- That’s it, now the source is ready to be compiled!
3. Perform the Build
- The build itself is now rather unspectacular… It simply works
> cd magplip/source > vamos smake all_opt SAS/C_SMAKE 6.58 (27.12.96) Copyright (c) 1988-1995 SAS Institute, Inc. sc:c/sc INCDIR="INCLUDEASM:" INCDIR="include:" INCDIR="netinclude:" VERBOSE DEFINE MAGPLIP=1 OBJECTNAME MAGrt.o rt.asm No default scoptions file found SAS/C Amiga Compiler 6.58 Copyright (c) 1988-1995 SAS Institute Inc. asm "-dMAGPLIP=1" -iINCLUDEASM: -iinclude: -inetinclude: -oMAGrt.o rt.asm ... SLINK Complete - Maximum code size = 8824 ($00002278) bytes Final output file size = 8940 ($000022ec) bytes
- If everything went fine then the resulting binary resides in the magplip/devs/networks folder:
> ls ../devs/networks/magplip.device.000 -rwxr-xr-x 1 chris staff 8940 18 Dez 18:16 ../devs/networks/magplip.device.000*
- Ah! A fresh build of the driver… Now let’s create a 68020 version, too:
> vamos smake CPUSUFFIX=020 all_opt ... > ls ../devs/networks/magplip.device.020 -rwxr-xr-x 1 chris staff 8872 18 Dez 18:21 ../devs/networks/magplip.device.020*
- Finally, you can compare your new builds with the reference compiles I did on P-UAE and that are available in the plip2slip release:
> cmp ../devs/networks/magplip.device.000 ../../plip2slip-0.1/contrib/magplip/magplip.device.000 > cmp ../devs/networks/magplip.device.020 ../../plip2slip-0.1/contrib/magplip/magplip.device.020
- It really works! Same output generated on vamos!!
- Now its time to read the plip2slip docs on how to actually use the driver on your real machine…
4. Some additional Notes
- While vamos now supports the typical builds on SAS C even with smakefiles, there are still things missing. Most notably, the internal Shell commands like Echo are not emulated yet. So the default/help rule in our project’s smakefile does not work. But the internal Shell commands and a more complete support for the typical CLI commands will be the next on my TODO list…
- Compared to last vamos versions I optimized the loading of native libraries (most notably sc1.library and sc2.library of sc) and that gave a real speed boost when calling the compiler.
- To better judge where the bottlenecks in the vamos emulation are, I added profiling support for the library calls. You can use the new -P switch and give the libraries you want to get detailed information for:

- That’s it for today! Enjoy vamos and if you already use it for doing your own “cross”-compiles then I’d really like to hear from your projects…
