Statically linking libc into my binary causes it to segfault


Statically linking libc into my binary causes it to segfault

I hope this helps . If you want to produce a static-linked binary, just add -static to the command line. You do not need libc.a there at all. What you're doing, adding libc.a without -static, produces a dynamic-linked binary, but pulls in some functions/files (whatever you reference, and everything those reference, recursively) from libc.a, and still also has the shared libc.so participating in your program. These are not generally able to work together.

wish helps you It's probably more feasible to create your own conditionally-compiled versions that use syscall() to call them directly.

I hope this helps you .
If I compile all the libraries statically will I avoid having to always gather the shared libraries when it core dumps
code :
Using 'getpwuid' in statically linked applications requires at runtime
the shared libraries from the glibc version used for linking.

will be helpful for those in need In case someone else runs into a similar problem, to the best of my knowledge, here are the answers to the four questions I asked. They are not encouraging.
1) You can't make it link with nonexistent libc.a files. Of course.
code :
a) Go to a newer version of QNX which uses a newer version of GCC
b) Get source for libc (and libm as it turns out) and build it with GCC 3.3.5.
   This one may pan out. Still waiting on QNX tech support.
c) Get already-built libraries from the QNX folks.
d) Don't use GCC 3.3.5 to build for Neutrino 6.3.2

I wish did fix the issue. I'm trying to compile glibc with debug symbols and use it for small application. So I downloaded and glibc, compiled without problems, installed in /custobuilds and now I'm compiling my own app: ,
get linked correctly
code :
crt1.o crti.o main.o -lc crtn.o

fixed the issue. Will look into that further The -static linker flag does not take any argument. It is a boolean flag that simply directs the linker to link no shared libraries, as documented
