Re: require your help

Hello henk, Sorry to bother you for this.I am a student and have little trouble in building osmocom.I require your help please. While building the project osmocom I get this error  saying  that the header file 'signal.h' is missing in osmocore.I am just uanble to figure it how it is unable to include the header file.By the way I am using the gnuarm-3.4.3 as shown on the osmocom-bb website.One more query please - as to exactly where do we have to put the armtoolchain(meaning which directory).Waiting eagerly for your reply. roy@roy:~/osmocom-bb$ cd src roy@roy:~/osmocom-bb/src$ make cd shared/libosmocore/build- target && ../configure \             --host=arm-elf-linux --disable-vty --enable-panic-infloop \             --disable-shared --disable-talloc --disable-tests \         CC="arm-elf-gcc" CFLAGS="-Os -ffunction-sections -I/home/roy/osmocom-bb/src/target/firmware/include -nostartfiles -nodefaultlibs" configure: WARNING: if you wanted to set the --build type, don't use --host.     If a cross compiler is detected then cross compile mode will be used checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for arm-elf-linux-strip... no checking for strip... strip checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... no checking for mawk... mawk checking whether make sets $(MAKE)... yes checking whether make sets $(MAKE)...
