Re: gcc 3.2 / glibc 2.2.5 Cross compile tools build

Jonathan Marks wrote: Hi, Firstly, thanks to Erik for compiling the tools, and providing the script so that it can be repeated. We had a couple of issues with the cross-3.2 build, prompting us to rebuild the chain; one issue is definitely fixed, the other will require more testing on our part to confirm that it is fixed. 1. gcc is compiled with pthread disabled in gcc. This creates libgcc_s.so without pthread support, which is a problem when throwing c++ exceptions in multithreaded apps. 2. When the cross-3.2 tool chain is used to build glibc for our arm targets, any program compiled to used shared libraries cored on the arm target. This is the case for both glibc 2.2.3 and 2.2.5. Compling glibc for the arm target using the cross-2.95.3 tool chain fixed this problem. It is suspected that this problem has to do with binutils 2.12 and greater. The toolchain we built uses binutils 2.11.2, rather than 2.13, used in Erik's build. We have not tested this by creating a new filesystem with the new libraries yet - feedback is welcome. If there is interest in this tool chain build, I'm happy to provide it and its build instructions. Perhaps it can be posted on the ftp site with the other tool-chains. I for one would be interested in the build instructions... Eli --------------------.

hi all, i build arm-linux-gdb at i386-linux host,but i can't use command "target sim",then i build a arm-elf version,so i can use "target sim". i have a simple hello world program compiled by arm-linux-gcc. but arm-linux-gdb helloworld target sim load run nothing happen just hangup.why can't print "hello world"?

Alternate bus master mode on PXA250

Hello, I am trying to use alternate bus master mode on the PXA-250 (B0 stepping), but haven't been successful yet. In include/asm/arch-pxa/pxa-regs.h, alternate bus master grant is defined to be alternate function 2 of GPIO 13. The PXA250 developer's manual, on the other hand, has contradictory statements: - pg. 6-70: enable MBGNT Alternate Function 3 - pg. 4-3: memory controller grant is ALT_FN_2_OUT If anybody has used alternate bus master mode, which of the above have you used ?

Re: Cross compile problem (gcc-3.2.1, glibc-2.3.1)

It seems that there are some bugs in gcc-3.2.1 arm portion. I cannot generate good kernel for StrongARM SA1110 Assabet with gcc-3.2.1. Zoltan Csizmadia wrote: Hi All, I try to cross compile a toolchain for ARM (DNP1110). When It tries to compile glibc, it doesn't find the headers (stdio.h, unistd.h). It seems there is no .../arm-linux/include directory (.../arm-linux/sys-include is created though). When is it created? My build-toolchain script is attached.
