Hi, I am using cross toolchain to compile OpenMPI 1.6.3 for ARM w/ following command line.
./configure --build=x86_64-redhat-linux --host=arm-unknown-linux-gnueabi CFLAGS="-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -mfpu=vfp -march=armv5te -mfloat-abi=hard" Then I got following error there: *** Assembler checking dependency style of arm-unknown-linux-gnueabi-gcc... gcc3 checking for BSD- or MS-compatible name lister (nm)... /home/huli/Projects/arm-devel/bin/arm-unknown-linux-gnueabi-nm -B checking the name lister (/home/huli/Projects/arm-devel/bin/arm-unknown-linux-gnueabi-nm -B) interface... BSD nm checking for fgrep... /bin/grep -F checking if need to remove -g from CCASFLAGS... no checking whether to enable smp locks... yes checking if .proc/endp is needed... no checking directive for setting text section... .text checking directive for exporting symbols... .globl checking for objdump... objdump checking if .note.GNU-stack is needed... yes checking suffix for labels... : checking prefix for global symbol labels... checking prefix for lsym labels... .L checking prefix for function in .type... # checking if .size is needed... yes checking if .align directive takes logarithmic value... yes configure: error: No atomic primitives available for arm-unknown-linux-gnueabi Is there any good way to fix that? Thank you very much. Eric
