The patch below actuallly consists of two patches: 1) moving librpc to c/src/librpc similar to what has been done to librtems++ 2) reworked configure scripts, many safety and dependency checks added to aclocal/*.m4 macros + configuration fixes. To apply: mkdir c/src/librpc mkdir c/src/librpc/src cp c/src/lib/librpc/*.c c/src/librpc/src cp c/src/lib/librpc/Makefile.in c/src/librpc/src mkdir c/src/librpc/include mkdir c/src/librpc/include/rpc cp c/src/lib/include/rpc/* c/src/librpc/include/rpc patch -p1 < ../rtems-rc-19990820-7.diff rm -rf c/src/lib/librpc rm -rf c/src/lib/include/rpc ./autogen The additional checks in aclocal/*m4 macros add rather restrictive, sometimes unnecessarily restrictive constraints on the sequence of how macros can be used in a configure.in script. Adding them has let my problems with some more complicated configuration options vanish. Apparently some macros had not been in the required order . ---- Now I still get some linking errors for some cpus and bsps, esp when linking cdtest, but also at other locations: e.g. this happens for mips64orion/p4600: # make[5]: Entering directory `/lfs/poseidon/users/rtems/src/multi/build/mips64orion-rtems/c/p4600/tests/samples/hello' /opt/rtems/bin/mips64orion-rtems-gcc --pipe -B../../../../../../p4600/lib/ -specs bsp_specs -qrtems -DP4000 -DCPU_R4000 -DP3_DIAG -D_R4000 -D__mips=3 -mcpu=4600 -G0 -I../../../../../../p4600/lib/include/networking -g -Wall -ansi -fasm -O4 -fomit-frame-pointer -o o-p4600/hello.exe o-p4600/init.o ../../../../../../p4600/lib/no-dpmem.rel ../../../../../../p4600/lib/no-event.rel ../../../../../../p4600/lib/no-msg.rel ../../../../../../p4600/lib/no-mp.rel ../../../../../../p4600/lib/no-part.rel ../../../../../../p4600/lib/no-signal.rel ../../../../../../p4600/lib/no-timer.rel ../../../../../../p4600/lib/no-rtmon.rel /opt/rtems/mips64orion-rtems/lib/libc.a(dtoa.o): In function `_dtoa_r': /opt/hermes/embedded/build/build-mips64orion-tools/mips64orion-rtems/newlib/libc/stdlib/../../../../../src/newlib/libc/stdlib/dtoa.c:348: relocation truncated to fit: R_MIPS_LITERAL no symbol /opt/hermes/embedded/build/build-mips64orion-tools/mips64orion-rtems/newlib/libc/stdlib/../../../../../src/newlib/libc/stdlib/dtoa.c:348: relocation truncated to fit: R_MIPS_LITERAL no symbol /opt/hermes/embedded/build/build-mips64orion-tools/mips64orion-rtems/newlib/libc/stdlib/../../../../../src/newlib/libc/stdlib/dtoa.c:348: relocation truncated to fit: R_MIPS_LITERAL no symbol collect2: ld returned 1 exit status # mips64orion-rtems-gcc -v Reading specs from /opt/rtems/lib/gcc-lib/mips64orion-rtems/2.95.1/specs gcc version 2.95.1 19990816 (release) # mips64orion-rtems-ld -v GNU ld version 2.9.5 (with BFD 2.9.5)
