Hi,
I get the following error:
"linker input file unused because linking not done"
When executing the following:
1)
g++ -c -fPIC -Wall ${CFLAGS} ${INCLUDES} ${LDFLAGS} a.cpp
I am trying to create an object file that is linked statically linked to libraries in a 3rd party library, so that I can later execute the command:
2)
I have been searching for this a bit on Google, and there are also some topics on StackOverFlow but they don't answer the main question: Why sometimes, under GCC on LINUX (and I mean Linux since on MinGW it doesn't happen with the SAME code), an application compiles and links correctly with other libraries, without any errors and then, on execution time, undefined symbols are thrown?
Why wasn't t
I'm trying to compile my project in Eclipse.
However, it says that the main() is defined more than once.
recently i was been to an interview to an automotive company, they have posed me a question that what section of compiler must be changed if the target is changed.
ie,if ur compiler is meant for generating executable to a 8051 target what changes do you do to make it flexible to generate the executable even to AVR, will you change the preprocessor,or the assembler or the linker or what....how
The linker produces this kind of output
/var/tmp/ccITB4j2.o: In function `main':
/var/tmp/ccITB4j2.o(.text+0x4): undefined reference to `myFunction(void)'
How can I find out the line of source code corresponding to the instruction at .text+0x4 where the function is actually invoked?
To My knowledge, the initialization order of shared libraries should be decided by their dependency relationship.
for example, a program links to libA, libB and libC. libA uses something in libB, and libB uses something in libC. so the initialization orders would be libC, libB and then libA.
I am reading:
http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html
It first suggests:
In combination with -flto using this option(-fwhole-program) should not be used.
I'm having trouble installing the packages, both are giving me the following error:Linking d2x-rebirth ...
/usr/bin/ld: main/render.o: undefined reference to symbol 'sinf@@GLIBC_2.2.5'
/usr/bin/ld: note: 'sinf@@GLIBC_2.2.5' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation

I get through the autogen and configure steps.
