Help on building the OpenBTS / OsmoBTS Transceiver branch
by . 22 Jul '21

22 Jul '21

Hello, I'm trying to build the transceiver branch for Calypso phones. I installed all OsmocomBB dependencies (including libosmocore) and i sucessfully built and installed libosmo-dsp from the Git repo. My ARM toolchain is from here: https://developer.arm.com/tools-and-software/open-source-software/developer… . When building, however, the compiler fails with: arm-none-eabi-ld: comm/libcomm.a(msgb.o):~/trx/src/target/firmware/comm/msgb.c:35: multiple definition of `tall_msgb_ctx'; ../../shared/libosmocore/build-target/src/.libs/libosmocore.a(msgb.o):(.bss+0x0): first defined here Makefile.inc:135: recipe for target 'board/compal_e88/hello_world.highram.elf' failed I tried both sylvain/testing and jolly/testing branches. What seems to be the problem? Thanks!
