Is there any example of compiling with a library (.a) file on SoC?

Jump to solution

On the windows7 PC, the compiler is: 'Invoking: GCC C Compiler 4 [arm-linux-gnueabihf]'

 

I am trying to use Pth, and I can certainly configure and make it on the de10-nano itself, however the libpth.a file it produces does not work on the windows7 PC build environment. I notice the compiler on the de10-nano itself is: gcc (Linaro GCC 6.2-2016.11) 6.2.1 20161016

 

I thought I could just copy the libpth.a file and link it - but the build environment cannot find file (even though I tell it where it is) - the error may be that the .a file is not ABI compatible?

 

So - the cut this short - an example of building a hello world with a library linkage would be ideal.

I found the clue here: https://developer.arm.com/docs/100070/latest/image-structure-and-generation/specifying-user-librarie...

               You can use the

--library=name

 

option to specify static libraries, libname

.a.

So - even though the actual filename is libpth.a - however the build tool only works if I say it is: pth

the tool adds the lib at the front and the .a at the end, and will not countenance the user supplying the full (and valid!) filename!?!?!

good grief.

I should note that hello_world compiles fine and targets down onto the de10-nano - but of course it is only a single source file. How to incorporate big lumps of 3rd party code (such as a static library) is what I am missing.
