What happened to FN-1824? These options allow multiple definitions and the first definition will be used. --allow-shlib-undefined --no-allow-shlib-undefined Allows or disallows undefined symbols in shared libraries. This was introduced to select the old O(n^2) algorithm for link map file generation, rather than the new O(n) algorithm which uses about 40% more memory for symbol storage. The paths can also be specified in a link script with the "SEARCH_DIR" command. http://kelcours.com/cannot-find/gcc-cannot-find.html

Unix linkers allow this somewhat sloppy practise, but linkers on some other operating systems do not. Browse other questions tagged linker cross-compiling or ask your own question.
This option is only meaningful on ELF platforms which support shared libraries. --dynamic-list=dynamic-list-file Specify the name of a dynamic list file to the linker. Usually the last step in compiling a program is to run ld. share|improve this answer edited Nov 23 '12 at 9:51 Andro Selva 35.7k33146199 answered Nov 23 '12 at 9:30 Ester 111 add a comment| up vote 0 down vote Have you not
This option should be used with caution as it overrides the search path that may have been hard compiled into a shared library. Passing "none" for style disables the setting from any "--build-id" options earlier on the command line. Many of the top ISVs run their applications through some form of testing. Ld Cannot Find All -rpath arguments are concatenated and passed to the runtime linker, which uses them to locate shared objects at runtime.
With that said, ISVs vary wildly on the processes they use to add support of a new OS release level. Undefined Reference To `__init_array_start' When running a 64-bit C++ application using C++ shared libraries and exception handling, the application crashes. The assumption is that the user knows what they are doing and deliberately wants to link in these unknown input files.

But there are some situations when using the GCC compiler might be more appealing. As an example, on glibc, compiling for mips64r2, N64 ABI, little endian; I put libraries like libc.so in
Specifying "--exclude-libs ALL" excludes symbols in all archive libraries from automatic export. It is mainly useful for building shared libstdc++. --dynamic-list-cpp-typeinfo Provide the builtin dynamic list for C ++ runtime type identification. --check-sections --no-check-sections Asks the linker not to check section addresses after Undefined Reference To `__libc_csu_init' They may follow, precede, or be mixed in with command-line options, except that an object file argument may not be placed between an option and its argument. Relocation R_x86_64_32 Against Can Not Be Used When Making A Shared Object; Recompile With -fpic AUDITLIB is not checked for existence, nor will it use the DT_SONAME specified in the library.

On AIX 5.2 and higher, the default is -mcpu=powerpc -- this code will work on pSeries PowerPC processors. This option is only meaningful on ELF platforms which support shared libraries. -Bstatic -dn -non_shared -static Do not link against shared libraries. Is privacy compromised when sharing SHA-1 hashed URLs?
gcc) then all the linker command line options should be prefixed by -Wl, (or whatever is appropriate for the particular compiler driver) like this: gcc -Wl,--start-group foo.o bar.o -Wl,--end-groupThis is important, On AIX, compiling code of the form: extern int foo; ... The default behaviour can be restored with the option --no-fatal-warnings. --force-exe-suffix Make sure that an output file has a .exe suffix. In this article, we will be discussing GCC versions 3.3.4 and all versions of 3.4 on AIX versions 5.1, 5.2 and 5.3.Comparing GCC compiler to XL C/C++ compilerXL C/C++ Enterprise Edition
They assign space to common symbols even if a relocatable output file is specified (with -r). your PREFIX is not correct WRT your --with-build-sysroot and/or --with-sysroot= MULTILIB_DIR is supposed to be used for mulitilib setups (in the gcc sense) but since it was apparent back than that In System V the names of all shared libraries listed on the command line are saved in the output file for possible use at load-time. check over here There are four possible values for method: ignore-all Do not report any unresolved symbols.
The listing is printed on stderr. What have I got wrong here? With --no-copy-dt-needed-entries specified on the command line however any dynamic libraries that follow it will have their DT_NEEDED entries ignored. For anyone else who encounters "Permission denied" after compiling or linking an executable, the ticket may be specifying the dynamic linker as Matthew explains.
For example, on SunOS, ld combines duplicate entries in the symbol string table. style can be "uuid" to use 128 random bits, "sha1" to use a 160-bit SHA1 hash on the normative parts of the output contents, "md5" to use a 128-bit MD5 hash The symbol alignments considered are sixteen-byte or larger, eight-byte, four-byte, two-byte, and one-byte. Doing this may, for example, trigger linking of additional modules from standard libraries. -u may be repeated with different option arguments to enter additional undefined symbols.
The default behaviour is to report errors for any undefined symbols referenced in shared libraries if the linker is being used to create an executable, but to allow them if the Description ld combines a number of object and archive files, relocates their data and ties up symbol references.

Once you have GCC installed, you can use it to compile the newer GCC version on your AIX system. There are three kinds of global symbols, illustrated here by C examples: int i = 1; A definition, which goes in the initialized data section of the output file. But if it is set then it is used to set the contents of libc.so while MULTILIB_DIR is still used when determining where to install the actual libraries. Maybe Mandrake does this for some reason. [I've looked into the contents of glibc-devel rpm and there is only the .so, which is the script which points to both a .so
Hope this helps, Best regards, Tom. GO OUT AND VOTE Why is looping over find's output bad practice? The optional demangling style argument can be used to choose an appropriate demangling style for your compiler. simply doing gcc hello.c -o hello should work.
Two notes when using this option from gcc: First, gcc doesn't know about this option, so you have to use -Wl,-whole-archive. GCC for AIX does not support -msoft-float fully. GCC is developed through an open source environment, as are all the GNU tools, and it supports many platforms including AIX.
