Ok, so after some trial and error I've finally found the correct combination of gcc & glibc that works for my device :). Thanks a lot to everyone who helped me while I was trying to build the toolchain. The toolchain that works for me has gcc3.3.2 (with the patch for softfloat) & glibc2.3.2. I can't use gcc3.4 because my Qt code doesn't compile with version 3.4 of the compiler. I have to use a particular version of Qt because that's what the device supports. I've been able to build and test this toolchain using crosstools-0.42, however when trying to build the same using the sb-toolchains scripts the build fails :(. The error message I get is pasted below, would appreciate it if someone could help me get past this problem. Perhaps something is not correct in my config script, the conf file I am using is also attached with this email.
I am able to build the toolchain using crosstool within scratchbox on
the host target. After making some modifications to the toolchain dir
generated (eg creating compiler-name, target_setup.sh, making symlinks
for sbox-arm-linux-xxx etc) I am able to create a target for my
toolchain and build code for my device. However I want to use
sb-toolchain to build my toolchain because it will build and install
all the other utilities needed (like gdb,gdbserver, strace etc) and do
the complete post-build configuration. Since I've done all the
configuration manually I don't know yet if I've done everything needed
and if I have done it correctly.
Another small question I have is: Is is possible to have a script that
gets executed everytime a target is selected? For instance I have some
other libraries, not part of the toolchain that I want to have in the
LD_LIBRARY_PATH. I don't want to put this in my .bashrc since the
configuration is specific only to my toolchain. Currently I execute a
script manually after I select my toolchain.
sb-toolchain build error pasted below and my .conf file is attached.
Thanks!
