Re: toolchain for c++ on coldfire

Hi Greg,

infinite thanks.

Do you maybe have also the

gcc-5.3.0-fix-libgcc-build.patch ?

thanks

Regards,

Angelo

Dear Greg and all,

i am building from some time some c++ apps for mcf5307.

At the time being, with the toolchain m68k-uclinux-20101118 i
get

some errors, like usleep not declared, even including
<unistd.h>,

as

88:15: error: ‘usleep’ was not declared in this scope

Actually, the only toolchain i can use successfully for c++

apps on mcf5307 is an old

Sourcery_CodeBench_Lite_for_ColdFire_uClinux

But we know they are no more available / open. Do you know any
other

alternative ? Or a guide i can use to prepare a c,c++ toolchain

for uClinux (then i can make it available) ?

Attached is a build script I use to build m68k-uclinux toolchains.

Most recently I have built and am testing a gcc-5.3 based
toolchain.

The elf2flt package referenced in this script was just a snapshot

of the github uclinux/elf2flt tree on that date.

I don't know if it will work any better for you with c++ apps,

but it is worth a try.

Note that gcc-5.3 will produce broken non-MMU m68k linux

for kernel versions older then 4.5 (due to code generation

issues with the signal handling code). So keep that in mind

if you are compiling kernels with it.

Regards

Greg
