Mity CPU Platforms » MityDSP-L138 (ARM9 Based Platforms)

I'm not familiar with libsodium. Could you provide a link to the source your building? How you are trying to build it? The full build output attached in a text file. Anything else you think will be helpful.

Which toolchain are you using?

https://github.com/jedisct1/libsodium/releases is the source location.

I created the CCS project as shown in the "startup" wiki for the MityDSP.
In C/C++ Build - Discovery Options - Cross G++ Compiler - Compiler invocation command I have "arm-angstrom-linux-gnueabi-g++"
In C/C++ Build - Discovery Options - Cross GCC Compiler - Compiler invocation command I have "arm-angstrom-linux-gnueabi-gcc"

The default way to compile the library looks like 'automake'. So there must be some sort of #defines that are set to configure the compile. I am unfamiliar with that tool.

If this project is not really designed to work with the MityDSP tool set, then that's fine we will try something else.

Thanks.

I tried cross compiling and was able to build the library.

ok that looks so easy. Thanks for the details. So you did not use the Code Composer Studio at all. I will try this and also try some of these settings in CCS, but if that fails, then just use the command prompt method.

1. This failed, with error about "--specs=nosys.specs"
   $ export LDFLAGS=
   $ ./configure --host=arm-angstrom-linux-gnueabi

Right. There might be a way to do the configure with CCS but I've not tried.

$ export LDFLAGS='--specs=nosys.specs' >>> So I guess this is not needed but that I can just 'export LDFLAGS=' and then run the ./configure

LDFLAGS shouldn't be set by default. So you probably don't have to set it to anything.

$ export CFLAGS='-Os' >>> I looked at the installation page and can now sort of follow what they are talking about.
$ ./configure --host=arm-angstrom-linux-gnueabi >>>>> Great that you knew to just ignore the '--specs=nosys.specs' and I would have assumed something was wrong with my system.

I had to look in the config.log file for the error message. I'm guessing the --specs thing is for newer toolchains.

1. This failed, with error about "--specs=nosys.specs"
   $ export LDFLAGS=
   $ ./configure --host=arm-angstrom-linux-gnueabi

These instructions worked for me. Thanks.
