[SOLVED] Compiling GCC for MSP430 Microcontrollers

Hello everybody,
I am new here in the Forum, so I hope this is the right place where to post my question.

Right now I am trying to compile Ti/RedHat MSP430 support for GCC. I have installed all the support packages needed (I have checked what ./configure is looking for while creating the make file).

This is the configuration parameters I use and the subsequent invocation of make:

../sources/tools/configure --target=msp430-none-elf --prefix=/opt/gcc-msp430 --enable-languages=c,c++ --disable-werror --disable-sim --disable-nls --disable-libssp
make all -j1

However the build breaks with this message:

/usr/bin/ld: cannot find -lexpat
collect2: error: ld returned 1 exit status
Makefile:1236: recipe for target 'gdb' failed
make[2]: *** [gdb] Error 1
make[2]: Leaving directory '/home/alessandro/msp430-build/gdb'
Makefile:13776: recipe for target 'all-gdb' failed
make[1]: *** [all-gdb] Error 2
make[1]: Leaving directory '/home/alessandro/msp430-build'
Makefile:859: recipe for target 'all' failed
make: *** [all] Error 2

I must point out that the expatlib is correctly installed:

[root@athanasius lib]# ls -alhg libcurl.so*
lrwxrwxrwx 1 root   16 Apr 22 15:53 libcurl.so -> libcurl.so.4.3.0
lrwxrwxrwx 1 root   16 Apr 22 15:53 libcurl.so.4 -> libcurl.so.4.3.0
-rwxr-xr-x 1 root 512K Apr 22 15:53 libcurl.so.4.3.0

also ldconfig finds the library:

[root@athanasius msp430-build]$ ldconfig -v | grep expat
	libexpat.so.1 -> libexpat.so.1.6.0

I can not figure out why ld does not find the library, maybe someone already had a similar issue in the past and hopefully can help me.

Thank you!

Re: [SOLVED] Compiling GCC for MSP430 Microcontrollers

Welcome to Arch.  Out of curiosity, is there a reason you are not using msp430-gdb from the AUR?

A quick look at the AUR shows a fair number of packages supporting that neat little processor.  I like the FRAM based parts.

Re: [SOLVED] Compiling GCC for MSP430 Microcontrollers

Hello ewaller,
thank you for your answer. I have no compelling reason to not use the AUR packages, apart from:

• the gcc I am trying to compile is a TI initiative, a good news and maybe the future considered the little activity on the user supported msp430-gcc

• the learning experience of compiling gcc and maybe preparing an AUR script

In the meantime I will test the AUR sourced msp gcc, however I will keep trying to get to compile the TI version. So I am still open to any hints that might help me to solve this problem.

By the way, I am also interested in the FRAM memory, I guess it has other interesting features: I have just started studying this MCU.

Re: [SOLVED] Compiling GCC for MSP430 Microcontrollers

Hello everybody,
I have managed to compile GCC for MSP430. I am posting my solution, maybe someone else can find it useful.
On this page of sourceware https://sourceware.org/gdb/onlinedocs/g … ments.html is described a switch for ./configure to specify a non standard location for libexpat:

--with-libexpat-prefix

So I have downloaded libexpat sources, compiled and installed them. By default it goes into /usr/local/lib/.

The next step is to reconfigure and build the new gcc make with:

../sources/tools/configure --target=msp430-none-elf --prefix=/opt/gcc-msp430 --enable-languages=c,c++ --disable-werror --disable-sim --disable-nls --disable-libssp --with-libexpat-prefix=/usr/local/lib/
make all -j1
make install

All the binaries will be installed in /opt/gcc-msp430/ the next step is to install the supporting header files (download them from the Texas Instrument website) with:

unzip msp430-support-files.zip
cd msp430-support-files/
chmod -R 755 *
cp *.ld /opt/gcc-msp430/msp430-none-elf/lib/430
cp *.h /opt/gcc-msp430/msp430-none-elf/include

Maybe this solution is a bit hacky but it works! I'll try to make an AUR script by next week.

Regards,
alva
