I can compile but not link my xenomai app. I get: /usr/bin/ld: skipping incompatible /usr/xenomai/lib/libtrank.so when searching for -ltrank /usr/bin/ld: skipping incompatible /usr/xenomai/lib/libcobalt.so when searching for -lcobalt etc.
I am testing xenomai 3.1 with x86-64 bit kernel 4.19.89 (I am porting my xenomai 2.6 codebase to xeno 3.1). I have compiled the kernel OK with 32 bit emulation support (CONFIG_IA32_EMULATION=y), as I must run my very large legacy xenomai 2.6 codebase as 32 bit. The xenomai testsuite latency, clocktest, switchtest apps run fine, BTW. Is the problem that the xenomai libs like cobalt are 64 bit only? Did I omit some xenomai configure option to support 32 bit xenomai apps ? Here is an example of the kind of gcc command line my Makefile puts out: gcc -g3 -m32 -I/usr/xenomai/include/trank -D__XENO_COMPAT__ -I/usr/xenomai/include/cobalt -I/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -fasynchronous-unwind-tables -D__COBALT__ -I/usr/xenomai/include/alchemy -I/usr/include/libxml2 -I/usr/xenomai/include/rtdm -I"../include/nanopb" -Xlinker -rpath -Xlinker /usr/xenomai/lib testapp.c ../modules/rtdinsync.h -Wl,--no-as-needed -ltrank -Wl,@/usr/xenomai/lib/modechk.wrappers -lalchemy -lcopperplate /usr/xenomai/lib/xenomai/bootstrap.o -Wl,--wrap=main -Wl,--dynamic-list=/usr/xenomai/lib/dynlist.ld -L/usr/xenomai/lib -lcobalt -lmodechk -lpthread -lrt -lfuse -pthread -Wl,--no-as-needed -Wl,@/usr/xenomai/lib/cobalt.wrappers -Wl,@/usr/xenomai/lib/modechk.wrappers /usr/xenomai/lib/xenomai/bootstrap.o -Wl,--wrap=main -Wl,--dynamic-list=/usr/xenomai/lib/dynlist.ld -L/usr/xenomai/lib -lcobalt -lmodechk -lpthread -lrt -lfuse -pthread -Wl,--no-as-needed -Wl,@/usr/xenomai/lib/cobalt.wrappers -Wl,@/usr/xenomai/lib/modechk.wrappers /usr/xenomai/lib/xenomai/bootstrap.o -Wl,--wrap=main -Wl,--dynamic-list=/usr/xenomai/lib/dynlist.ld -L/usr/xenomai/lib -lcobalt -lmodechk -lpthread -lrt -lfuse -pthread -lz -llzma -lm -ldl -Wl,--start-group -loshw -losal -Wl,--end-group -lm -o testapp thanks, -C Smith
