Good 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:

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,
