Description Anton Kochkov 2012-08-17 07:11:24 UTC
JWasm is a free MASM-compatible assembler with these features:

    native support for output formats Intel OMF, MS Coff (32- and 64-bit), Elf (32-and 64-bit), Bin and DOS MZ.
    precompiled JWasm binaries are available for DOS, Windows and Linux. For OS/2 and FreeBSD, makefiles are supplied.
    Instructions up to AVX are supported.
    JWasm is written in C. The source is portable and has successfully been tested with Open Watcom, MS VC, GCC and more.
    As far as programming for Windows is concerned, JWasm can be used with both WinInc and Masm32. Since v2.01, it will also work with Sven B. Schreiber's ancient WALK32.
    C header files can be converted to include files for JWasm with h2incX.
    JWasm's source code is released under the Sybase Open Watcom Public License, which allows free commercial and non-commercial use.

jwasm 2.8 ebuild

Probably not the cleanest ebuild, but the underlying source package doesn't conform to typical open-source packaging practices.  Copy the license text from into /usr/local/portage/licenses/sowpl to enable building.

updated ebuild

must build a 32-bit binary, even on AMD64

I'll try to add 2.10 to the tre today/tomorrow.

I didn't do x86 build yet. If you have issues with amd64 builds
let's try to look at them first.

Thanks guys!
