Paul Cevoli pcevoli at kvh.comGood morning,
Working with the simtrace2 code cross compiled for an a53 processor and am running into a few issues. This email summarizes the issues and am wondering if anybody has either resolved these or has any suggestions. The issues are
* Cross compiling errors with the simtrace2 host tools
* simtrace2-tool run time logging errors
Issue #1 simtrace2-cardem-pcsc.c app
Simtrace2 requires libosmocore. When trying to build the simtrace2 host tools neither tagged versions of libosmcore 1.5.1 or 1.5.2 will compile correctly. The only way to get the simtrace2 host tools to compile is to use commit cfea39ba. Otherwise the following syntax errors occur in the simtrace2-cardem-pcsc.c app. Is there some magic required to have the simtrace2 host tools compile with a tagged version of libosmocore?

Issue #2 simtrace2-tool
Simtrace2-tool has an assertion error in the osmo logging system, perhaps this is related to the question above about using tagged versions of libosmocore.
When trying to use the built version of simtrace2-tool the following stack track occurs:
$ simtrace2-tool -V 1d50 -P 60e3 -C 2 -I 0 -S 0 -A 10 modem sim-switch local

Adding the osmo logging initialization (listed below) does not, at first glance, appear to help
static struct log_info log_info = {};
rc = osmo_libusb_init(NULL);
if (rc < 0) {
fprintf(stderr, "libusb initialization failed\n");
return rc;
}
Thank you,
