Hello,
I am currently using Geisler’s RCC 1.2 and RTEMS 4.10. I am getting an
error after compiling my c files into object files, and then linking
them together. The error I get is:
/opt/rtems-4.10/sparc-rtems/leon3/lib/librtemscpu.a(dummy.o):(.data+0x2c):
undefined reference to `main'
collect2: ld returned 1 exit status
a likely reason for this error is that you don't have an application
configuration or the configuration is somehow incomplete or inconsistent:
https://docs.rtems.org/branches/master/c-user/configuring_a_system.html
You can look at the linker map file (GCC link option "-Wl,-Map,map.txt")
to figure out what pulled in dummy.o.
I am using “sparc-rtems-gcc“ to do the linking, and cannot seem to
figure out how to get around this problem. The file “librtemscpu.a” is
part of the prebuilt libraries included in the RCC 1.2 distribution, and
I cannot find any source code for this file to inspect the unresolved
reference to main. I am wondering if any of you have suggestions about
solving this issue or maybe have run into the same thing. Please let me
know.
I guess you can obtain the sources in an extra package. Working without
the RTEMS sources could turn out to be difficult in the long run.
