Myers 2011-02-17 18:38:18 UTC Fixed for 4.6, though I advise using -rdynamic or -Wl,-export-dynamic instead of this backwards-compatibility support for a previous accident of the implementation. If scriptfile does not exist in the current directory, "ld" looks for it in the directories specified by any preceding -L options. Terms Privacy Security Status Help You can't perform that action at this time. nodefaultlib Marks the object that the search for dependencies of this object will ignore any default library search paths. click site

If there is one, it will be used instead of the definition in the filter object. extern int i; An undefined reference, which does not allocate space. http://stackoverflow.com/questions/23200755/gcc-compiler-error-unrecognized-option-export-dynamic
The section containing the entry symbol and all sections containing symbols undefined on the command-line will be kept, as will sections containing symbols referenced by dynamic objects. If the required shared library is not found, the linker will issue a warning and continue with the link. -shared -Bshareable Create a shared library. This option is only effective if garbage collection has been enabled via the --gc-sections) option. I didn't specify that.
Can we restore this behavior to avoid regressions? > > If not, can we diagnose this invalid option then? For options whose names are multiple letters, either one dash or two can precede the option name; for example, -trace-symbol and --trace-symbol are equivalent. This option is only meaningful on ELF platforms supporting the rtld-audit interface. Use -Ur only for the last partial link, and -r for the others. --unique[= SECTION ] Creates a separate output section for every input section matching SECTION , or if the
The directories are searched in the order in which they are specified on the command line. Modified: trunk/gcc/ChangeLog trunk/gcc/common.opt trunk/gcc/gcc.c Comment 9 Joseph S. Sign in to comment Contact GitHub API Training Shop Blog About © 2016 GitHub, Inc. http://cboard.cprogramming.com/c-programming/126394-gcc-compiler-doesnt-know-parameter.html interpose Marks the object that its symbol table interposes before all symbols but the primary executable.
This option is only meaningful on ELF platforms which support shared libraries. -Bstatic -dn -non_shared -static Do not link against shared libraries. Another effect of the switch is to set the default hash table size to 1021, which again saves memory at the cost of lengthening the linker's run time. It will compile with clang/clang++, so that'd good. For example, --trace-symbol foo and --trace-symbol=foo are equivalent.
This is useful when generating huge relocatable files for downloading into certain real time kernels with the COFF object file format; since COFF cannot represent more than 65535 relocations in a Downloading llvm-3.2-x86_64-unknown-linux-gnu-4.2.tar.bz2.md5...

Aside from its flexibility, the GNU linker is more helpful than other linkers in providing diagnostic information. Is the NHS wrong about passwords? 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. nocopyreloc Disables production of copy relocs.
It does not affect how undefined symbols in regular object files are handled. The module names may be delimited by commas or colons, and must match exactly the filenames used by ld to open the files; for archive members, this is simply the member sorry. (rerun ccmake in paraview build dir and turn on hdf5 enable parallel). So you can fix this with your own means (e.g.

Similarly the runtime finalization of the object will occur after the runtime finalization of any other objects.
But the CFLAGS are not being used by configure via it's env, they're being passed to it as an arg. This can be useful when creating a dynamic binary and it is known that all the shared libraries that it should be referencing are included on the linker's command line. Can we force -e options to be passed down in their original joined/non-joined form? It is best to use it only when there are unavoidable circular references between two or more archives. --accept-unknown-input-arch --no-accept-unknown-input-arch Tells the linker to accept input files whose architecture cannot be
Debian distribution maintenance software pp. Already installed rbx-2.2.6 ruby-2.1.1. Thus the shared object name may be used to provide an alternative implementation of certain functions, perhaps for debugging or for machine specific performance. This is ignored for other object file formats. -h name -soname=name When creating an ELF shared object, set the internal DT_SONAME field to the specified name.
This is only useful for a few object file formats.
