Pantheios INSTALL.TXT says:
Open a command shell in the appropriate directory that matches your compiler: ...
My compiler is Clang:
> gcc --version
Apple LLVM version 5.1 (clang-503.0.40) ...
Target: x86_64-apple-darwin13.3.0
Which of the compiler settings files in Pantheios 1.0.1-beta214 is the most appropriate?
You can use homebrew to install an older version of gcc (e.g., gcc-4.2) and use the matching Pantheios makefile, like this:
brew install gcc42
make CC=gcc-4.2
However, as far as I have been able to tell, Pantheios is not going to be buildable on a recently-updated system. For example, as of today, building on OSX looks like this:
04:29:23 ~/src/pantheios-1.0.1-beta214/build/gcc42.unix$ make CC=gcc-4.2
Ensuring all STLSoft C source files are in UNIX format
sed: RE error: illegal byte sequence
make: *** [/Users/username/src/stlsoft-1.9.118/include/stlsoft/internal/dos2unix.has.been.performed] Error 1
I have also tried building on Windows as recently as 6 months ago and lost a good bit of time on it before giving up.
The library hasn't been updated in a very long time and the author has very little online activity since then. I call that "abandoned software". Building will very likely require a non-trivial amount of work on your part. I'd highly recommend severing the dependency on STLSoft if you do because it also appears to be abandoned.

I am trying to build a haskell project from Ludum Dare, but whenever I attempt the build I get an error message saying the object file has too many sections. Here is the error:

I am using stack 2.3.3 and Windows 10. The project uses the vulkan library.
I tried adding -opta-mbig-obj, but gcc then failed with error: unrecognized command line option '-mbig-obj'
It looks like you may need to try explicitly using the “large object” file format, which I believe you can do by adding -opta-mbig-obj or -Wa,-mbig-obj to the GHC flags in the project’s build config (package.yaml or .cabal file) to add -mbig-obj to the assembler options. You may also need to add --oformat pe-bigobj-x86-64 to the linker flags, using (I think) -optl--oformat -optlpe-bigobj-x86-64 or -Wl,--oformat,pe-bigobj-x86-64. Are you using a 32-bit MinGW? I would expect MinGW64 to handle this by default. (And I’m not actually sure whether 32-bit supports these flags, so you may need to upgrade anyway.)
Since about a year ago (https://gitlab.haskell.org/ghc/ghc/-/commit/1ef90f990da90036d481c830d8832e21b8f1571b) GHC already uses the -mbig-obj and --oformat,pe-bigobj-x86-64 when assembling and linking on 64 bit MinGW. Adding these flags manually will not help on recent GHC versions.
I was able to replicate this problem for both the sdl2 and vulkan Haskell packages using Stack, however neither of them exhibit this issue when compiled with Cabal (and --enable-split-sections) on Windows; this looks to be a bug in stack.
I am trying to install a program and when I run make or make -f Makefile (following the installation instructions) I get the following output:
g77 -O5 -Wall -c prep_output.f -o prep_output.o
dyld: Symbol not found: ___keymgr_global
Referenced from: /usr/local/bin/g77
Expected in: /usr/lib/libSystem.B.dylib
make: *** [prep_output.o] Abort trap: 6
I am working on a macOS Mojave 10.14.6. Following some other proposed solutions in similar problems, I've already installed Command line tools in my Xcode but that didn't do the trick. Any suggestions please??
Thanks in advance
EDIT:
I got rid of g77 and installed a compatible version of gcc (gcc8) through MacPorts. After running the make command I get the following:
g77 -O5 -Wall -c prep_output.f -o prep_output.o
make: g77: No such file or directory
make: *** [prep_output.o] Error 1
So I guess the program still needs the g77 setup? This is the program btw ([http://www.cfht.hawaii.edu/~arnouts/LEPHARE/install.html]). Is there a way to rely to the gfortran compiler for building the program?
Thanks in advance
P.S. I noticed that when I install g77 I get the following error:
x usr/local/: Can't set user=0/group=0 for usr/local`
`tar: Error exit delayed from previous errors.
However it still installs g77..
The error message indicates that your installation of g77 is broken. This has nothing to do with make or the particular project you're trying to build, except inasmuch as the project is trying to use g77 in the first place. That is a bit surprising, actually, since g77 has been obsolete for years (gfortran is the current GNU Fortran compiler), but I'm uncertain what exactly to expect from XCode in this area.
On the other hand, since the full path to the binary is /usr/local/bin/g77, I'm further inclined to think that you're not using XCode for this at all. Possibly you've dumped a g77 built on some other system into your /usr/local/bin, and it's not compatible with your Mojave system.
Your best bet is probably to
Get rid of your broken g77 installation.
Install Fink or MacPorts, or a similar project.
Install the Fink / MacPorts / whatever package for gfortran (maybe gcc-gfortran or similar in some of those) to get a working Fortran compiler.
Rely on that compiler to build your project.
I eventually want to use valgrind to find what is causing the occasional bizarre output in a C program which refines a model against experimental data using OpenMP parallel programming.
To avoid the use of the nominal gcc (ie clang) compiler, I used brew to install gcc-4.9 on my MacPro running Yosemite (OS x 10.10.5). However, when trying to compile my program with gcc-4.9, with or without -fopenmp, I get numerous error messages of the type:
/var/folders/qc/1j0gr_l48xnfd9001s6tt6f80000gn/T//ccRxnrnU.s:30597:suffix
or operands invalid for `movq'
I have no idea what the problem triggering these error messages is. Can anyone help?
The following summarises what was worked out in the comments section and did lead to the issue being resolved. Not all steps may be necessary, but most are probably good practice.
Step 1 - Clean up
If you have been trying lots of different, potentially incompatible, methods to get OpenMP set up, it is probably a good idea to clean them up first. So, something like:
brew rm --force gcc # or maybe gcc#4.9
Step 2 - Update Xcode and Command Line Tools
If you have upgraded macOS since installing Xcode, it is probably advisable to update Xcode and its "Command Line Tools"
Consider uninstalling and re-installing Xcode - it is available for free from the App Store.
Update/install the "Command Line Tools" after installing/updating with:
xcode-select --install
Step 3 - Install gcc
Now, try installing gcc afresh, ensuring that you use the --without-multilib option:
brew install gcc#4.9 --without-multilib
Hopefully you can now compile OpenMP code with:
/usr/local/bin/gcc -fopenmp program.c -o program
I am unsure exactly why the --without-multilib option is needed and prefer to quote #hristo-iliev:
Multilib usually refers to the coexistence of both 64-bit and 32-bit
versions of each library so that 32-bit software could be run on
64-bit OS. In the GCC case that probably refers to having all GCC
runtime libraries in "fat" Mach-O format, i.e. versions for both i386
and x86_64 in the same shared library file. It could be that libgomp
(the GNU OpenMP runtime library) cannot be built in such a way.
See this question.

I'm working on touching up homebrew's (OS X package manager) llvm formula. Unfortunately, something about the parts I added broke the build in a way I just cannot figure out.
tl;dr ld asks for a library containing a _wordexp symbol for iOS simulator, and I have absolutely no clue where it is, if it exists
Compilation consistently fails for me when the compiler is attempting to link the address sanitizer dylib for iOS Simulator.
Reproduction steps (OS X only as far as I know, don't have *nix systems handy):
install homebrew if it isn't already installed
replace homebrew's llvm formula with the WIP one above
Run brew install llvm --with-clang --with-lldb --verbose --debug
wait for the build to fail and ask you what to do
Drop into a debug shell
cd to projects/compiler-rt/lib/asan/CMakeFiles/clang_rt.asan_iossim_dynamic.dir
add the following line to link.txt
-Wl,-syslibroot /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk
go back up to asan
Run make
At this point on my machine, something like this pops up:
Undefined symbols for architecture x86_64:
"_wordexp", referenced from:
_wrap_wordexp in asan_interceptors.cc.o
substitution_wordexp in asan_interceptors.cc.o
(maybe you meant: _wrap_wordexp)
ld: symbol(s) not found for architecture x86_64
I thought that it was just a matter of adding another folder to the linker search path. Turns out it isn't that simple:
wordexp.h is in <path-to-iPhoneSimulator.sdk>/usr/include, but running
find . -type f -name "*.dylib" -print0 | xargs -0 nm | grep -n "T _wordexp" -B <large number> | less
in Xcode-beta.app showed that the only .dylibs in Xcode that exported a _wordexp symbol were in the WatchSimulator.platform folder
Running the same command in /usr showed that 3 libraries in /usr/lib/system exported _wordexp (libsystem_asl, libsystem_c, and libsystem_blocks), but the linker doesn't seem to care when I add /usr/lib/system to the search path even when the code is the x86_64 code it wants, and the corresponding dylibs I found for other platforms didn't contain _wordexp
Googling about about this particular symbol missing turned up mostly stuff about Apple implementing wordexp() with Perl
I think I remember seeing something in the llvm-dev mailing list archives about *BSD/OSX not implementing wordexp, but the header file is definitely there, wordexp() shows up in the manpages, and the functions declared in the header file seem to work just fine when compiling for OSX
The symbol is not in the libc++(abi) dylibs compiled earlier in the build
Every other part of the build compiles just fine except for the asan folder and its parents
What am I missing? Given that this error does not seem to be particularly common, there could be a chance it's my machine, but I'm hoping the chances are pretty low, because I wiped and reinstalled my computer this weekend.
(OS X 10.11, Xcode/CLT 7.1, mid-2012 Retina pro)
If more info is needed I'll be happy to provide it.
Edit 1: Simplified link.txt fix. Turns out setting sysroot for clang++ doesn't do so for ld
Turns out the error was a result of the way homebrew processed compiler flags. That and a few other problems have been fixed since, so this probably isn't too useful any more.
For those curious about how exactly this broke, homebrew tries to change compiler flags to suppress warnings and create a more consistent building experience. One of these changes was to remove any -isysroot or -system flags, because that was added by homebrew itself at a later stage. Unfortunately, homebrew assumed that only the OS X SDK would be used, so when the build expected to build something with the iPhone simulator SDK it was pointed to the OS X SDK.
I'm on freebsd and trying to run uhd from: http://www.ettus.com/download This should normally run under freebsd, but I encounter problems when I try to build it like specified here:
http://www.ettus.com/uhd_docs/manual/html/build.html#build-instructions-unix
I get:
[ 73%] Building CXX object examples/CMakeFiles/benchmark_rx_rate.dir/benchmark_rx_rate.cpp.o
Linking CXX executable benchmark_rx_rate
../lib/libuhd.so.003.000: undefined reference to `uhd::set_thread_priority(float, bool)'
collect2: ld returned 1 exit status
*** Error code 1
Now this seems to be a linker error, but how to get rid of it? I tried setting the path using ldconfig but this hasn't changed a thing. Maybe some of you have an idea where I could continue searching.
If i get it right, libuhd get's built earlier by this CMake script. If it's true, this error indicates bug in their CMakeLists.txt files.
It looks like you are building examples of using libuhd. I doubt you are need them. So, either look for switches in your CMakeCache.txt and regenerate Makefiles or hack CMakeLists.txt to not include examples dir.
Another thing you may try - set CMAKE_EXE_LINKER_FLAGS to -L/usr/local/include.
This is a perfect situation for creating a FreeBSD port. Since FreeBSD has its own consistent filesystem layout, compiler and linker flags often need to be modified (as noted by arrowdodger) slightly.
The ports system is a framework for persistently capturing those configuration changes and making any software package as easy to install as typing the commands:
cd /usr/ports/category/application-name && make install clean
In a perfect world, you would create the UHD port, submit it for review and addition to the tree. If you need help learning how to do that, the FreeBSD Porter's Handbook and the freebsd-ports mailing list are excellent resources.
