Cainiao's blob compilation-general Linux technology-Linux programming and kernel information. The following is a detailed description. System Configuration: fedora 7 + arm-linux-tools-20061213 + blob-for3000 + uClinux-dist-20041215
Compilation steps:
First, rewrite the blob program based on the hardware of the target system.
Compile uClinux-dist (obtain the Kernel configuration source file)
Then:
Configure the cross-compilation environment
# Tar zxvf arm-linux-tools-20061213.tar.gz
# Ls
Usr
# Cp usr/usr
/* This step is required. Instead of this step, the unzipped usr folder is directly written into the PATH, and the results can be correctly displayed using which, arm-linux-gcc-v, and so on, but it cannot be used to compile hello. the reason is that usr/local/arm-linux/lib/libm. so.6 is a link file. The link address is located in/usr/loacl in the system directory, rather than in usr/local */
