Re: [fpc-devel] ncurses example on arm linux uclibc
Hi Jonas
This is the gist of a Freenode chat on #uclibc
nataraj /usr/br-git-rf/usr/lib/libc.a(sigrestorer.os):(.ARM.exidx+0x0):
undefined reference to `__aeabi_unwind_cpp_pr1'
nataraj which lib is __aeabi_unwind_cpp_pr1, defined?
nataraj got this while trying to compile an app using freepascal arm
compiler built with arm-linux-uclibcgnueabi tool chain
nataraj jacmet,blindvt` ?
gustavoz nataraj: that's libgcc
nataraj http://pastebin.com/m4f18da1
nataraj gustavoz, means fpc dint use uclibc?
gustavoz nataraj: libgcc != glibc/uclibc
nataraj sorry, got it wrong
nataraj ok, where does it leave me and fpc on uclib?
gustavoz did you build/include libgcc in br?
nataraj Build/install a shared libgcc? yep
nataraj BR2_GCC_SHARED_LIBGCC=y
gustavoz it's likely fpc is failing at linking runtime libraries
needed by the toolchain
nataraj i can run plain hello world pascal programs
nataraj using writeln('hello world');
nataraj so it is a problem of fpc not br?
gustavoz very likely
gustavoz you've got that symbol in libgcc so fpc is failing to link it in
gustavoz you may need a command line switch for fpc to open it, it's
been ages since i've used fpc so i don't recall
gustavoz you may be able to set things right in fpc.cfg too
Any help?
regards

in
/usr/br-git-rf/lib it is in
libgcc_s.so.186bc W __aeabi_unwind_cpp_pr1
You need a T. U = undefined, i.e., that library uses that symbol, but does
not contain it. I guess W = weak reference (i.e., the library uses that
symbol, but it can also be loaded even if the symbol is not available, and
the code will check whether the symbol is available before using it).

As I said in my very first reply to you in this thread: No idea
whether these are part of libc or libgcc. You may also have to add
{$linklib gcc} to your program and -Fl/path/to/libgcc to your command
line.
When using --sysroot, you may have to cut the sysroot form the/path/
libgcc though.
