Hi list, Yesterday when I tried to to make a new build of sylvain/testing  I encountered following errors when running make(and also when running make HOST_layer23_CONFARGS=--enable-transceiver): -------------------------------------- make -C target/firmware CROSS_COMPILE=arm-elf- make[1]: Entering directory `/root/osmocom-bb/src/target/firmware' apps/trx/trx.c:22:22: inttypes.h: No such file or directory make[1]: Leaving directory `/root/osmocom-bb/src/target/firmware' make[1]: Entering directory `/root/osmocom-bb/src/target/firmware' apps/trx/trx.c:22:22: inttypes.h: No such file or directory make[1]: *** No rule to make target `apps/trx/trx.p', needed by `all'.  Stop. make[1]: Leaving directory `/root/osmocom-bb/src/target/firmware' make: *** [firmware] Error 2 ------------------------------------------- Master branch builds fine on backtrack 5 r2  and so did also Sylvain/testing earlier. Searching mailing-list gives  some info that removing inttypes.h can be done as that "is taken care of by upstrean libosmocore".However I have read that inntypes.h should exist. I tested and removed inttypes.h in trx/trx.c. Recompiling gives an error message about parse error before debug-message PRIu32 on line 69 in trx/trx.c. Commenting out that line makes it build, but as info obtained earlier I now guess I have also removed some key-functionality and my approach is wrong? Further searching gave some unclear/vague(mostly for other situations) hints that the line  #include <inttypes.h> could be replaced by: #ifdef HAVE_STDINT_H #include <stdint.h> #else #include <include <inttypes.h> #endif I tested replacing #include <inttypes.h>  by the abovein trx.c also but it didn't work. Any ideas or hints what migh be wrong? Enclosed is the full build-error-log from running without making any changes to inttypes.h. Regards erich
