CodeSourcery uclibc toolchain for mips_linux on timesys image doesn't run

[Alex Rahlis]

Hi All,

I am trying to compile and run a very simple “hello world” program with
CodeSourcery uclibc toolchain for mips_linux:

*mips-linux-gnu-gcc test.c -o s_test*



I am trying to run it on my target machine that has Timesys linux (also
uclibc), for some reason I am getting this error:

*./s_test*

*-sh: ./s_test: not found*



The same test runs fine when compiled with Timesys uclibc toolchain:

*mipsisa32r2-timesys-linux-uclibc-gcc test.c -o t_test*



I even reduced the test to minimal code, but still got the same result, here
is the minimal test code

*int main(int argc, char **argv)*

*{*

* return 0;*

*}*



It looks like the linux can’t find the “main” entry point or something…



I tried to run strace to get some more info, here is what I got:

*strace ./s_test*

*execve("./s_test", ["./s_test"], [/* 15 vars */]) = -1 ENOENT (No such file
or directory)*

*write(2, "strace: exec: No such file or dir"..., 40strace: exec: No such
file or directory) = 40*

*exit(1)*                                 *= ?*



when I do strace for the test compiled with Timesys toolchain I get (first
few lines):

*strace ./t_test*

*execve("./t_test", ["./t_test"], [/* 15 vars */]) = 0*

*old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x2aaad000*

*stat("/etc/ld.so.cache", 0x7f8709c0)    = -1 ENOENT (No such file or
directory)*

*open("/lib/libgcc_s.so.1", O_RDONLY)    = 3*

*….*



I run “nm” on both files and I attach the result here.

It looks like the not working Codesourcery test tries to run

*__libc_start_main*

While the working test runs

*__uClibc_main.c*
