Hi Gil,
It's nice to see someone using TI CGT!
I've been working on it but the current Zephyr code base has many GCC-ism's.
Most challenging part of it is the final linking. In parts, CGT's
pre-processor doesn't handle
.S with C includes, it expands ".text" into ". text" with a white
space between dot and alpha,
the linking commands assume c compiler with linker options, etc.
I've talked to Sebastian about it and he said he'd like to go with a
compiler translator,
a python script to translate a compiling commands to another. A
tentative code is at
https://github.com/zephyrproject-rtos/zephyr/issues/10182With the script. I've compiled all C code but haven't finished the
final linking.
just to note, currently the CROSS_COMPILE environment variable only works with a
tool chain with same prefix. ie) "armeb-eabi-". Check
cmake/compiler/gcc.cmake.
Regards,

Hi Flavio,
I also recorded some issues attempting to integrate TI compiler/toolchain:
https://github.com/zephyrproject-rtos/zephyr/issues/9284
I haven't gotten back to it as it's lower priority for the moment.

Hi Sebastian,
The in-tree documentation is lacking indeed, but I also wanted to know
whether people is trying to use other compilers and the problems they
are facing.
The work on MISRA-C and C99 conformance will make easier use different
tools -from code only perspective - and I'm trying to map what are the other
problems.
This is a known hole in our documentation.
To discover toolchains that have in-tree integrations see the contents of zephyr/cmake/toolchain.
Toolchains that are not integrated use CROSS_COMPILE, but using CROSS_COMPILE will only work for certain types of toolchains and certain types of Zephyr configurations.

Hi,
Guys I'm trying to have a list of supported compilers on Zephyr, but in
our wiki just mention about 3rd-party compilers but don't mention any
other than GNU ARM compiler.
If you are using a compiler different from our SDK, can you tell me so I
can catalog it. If you're just trying to use other compiler, please tell
me which problems you are facing.
