I'm trying to use Mono's mkbundle tool to compile a native app for ARM (RaspberryPi) from an AMD64 system (Ubuntu 14.04 running in a VM).
Mono version is 4.4.2.11 (latest, at time of doing this), installed from Mono's package repository, but also tried with 4.2.3.4.
I'm running:
export CC="/usr/bin/arm-linux-gnueabi-gcc"
export AS="/usr/arm-linux-gnueabi/bin/as"
/usr/bin/mkbundle --static --deps --skip-scan \
-o artifacts/MyApp \
bin/Debug/MyApp.exe bin/Debug/*.dll
This works fine if I run it on the RaspberryPi itself (though I don't need to set the CC and AS variables).
If I run it from my AMD64 VM, it eventually runs the command:
/usr/bin/arm-linux-gnueabi-gcc -o artifacts/MyApp -Wall \
-D_REENTRANT -I/usr/lib/pkgconfig/../../include/mono-2.0 \
temp.c \
-L/usr/lib/pkgconfig/../../lib \
-Wl,-Bstatic -lmono-2.0 -Wl,-Bdynamic \
-lm -lrt -ldl -lpthread \
temp.o
Which results in:
/usr/lib/pkgconfig/../../lib/libmono-2.0.a: error adding symbols: File format not recognized
collect2: error: ld returned 1 exit status
Realizing that the libmono-2.0.a comes from an architecture-specific package, I downloaded the armel architecture package from http://download.mono-project.com/repo/debian/pool/main/m/mono/ and extracted it in my home directory (so there is a /home/gregmac/libmono-armel/usr/lib/libmono-2.0.a), then tried:
/usr/bin/arm-linux-gnueabi-gcc -o artifacts/MyApp -Wall \
-D_REENTRANT -I/home/gregmac/libmono-armel/usr/include/mono-2.0 \
temp.c \
-L/home/gregmac/libmono-armel/usr/lib \
-Wl,-Bstatic -lmono-2.0 -Wl,-Bdynamic \
-lm -lrt -ldl -lpthread \
-v \
temp.o
I've also tried setting LIBRARY_PATH and LD_LIBRARY_PATH to /home/gregmac/libmono-armel/usr/lib, but always getting the same problem.
Full output (including -v option):
Using built-in specs.

I've also tried the same command but without --static, and get the same error, but about the .so instead of .a file:
/usr/lib/pkgconfig/../../lib/libmono-2.0.so: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
Am I missing something obvious here? Why is gcc still looking in /usr/lib/ instead of /home/gregmac/libmono-armel/usr/lib? Is there some other environment variable I should be setting so the original mkbundle command can invoke this correctly?

I have system with CentOS 6.4 and it comes with GNU Fortran (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18).
I am doing quadrupule precision calculation and for that I installed devtoolset-6 w/o a problem. Since the system has a default gcc/gfortran installed, i cleared the shell with
env -i bash
and following that i set the devtoolset-6 environment
scl enable devtoolset-6 bash
If i check the installed gcc and gfortran version, they are as following
gcc (GCC) 6.3.1 20170216 (Red Hat 6.3.1-3)
GNU Fortran (GCC) 6.3.1 20170216 (Red Hat 6.3.1-3)
so far so good. I also have a testing example given below
implicit double precision(a-h,o-z)
print * , ' i:'
read(5,*) i
if(i.le.0) stop
a=i
b=sqrt(a)
print * , b
c=b*b
print * , c
end
compiled with
gfortran -fdefault-real-8 -o test.exe test.F
When i try to compile i am getting the following error
(.text+0x20): undefined reference to main'
/tmp/cc7n6vIv.o: In functionljacoeff_':test.F:(.text+0xf0): undefined reference to _gfortran_transfer_real128_write'
test.F:(.text+0x16b): undefined reference to_gfortran_transfer_complex128_write'
test.F:(.text+0x1ea): undefined reference to `_gfortran_transfer_complex128_write'
collect2: error: ld returned 1 exit status
At first, i thought the _gfortran_transfer_real128_write function is not defined and checked the library comes with devtoolset-6 using default "nm" command and indeed that function is defined in libgfortran.a. After some debugging and more debugging i discovered the "-v" option and recompiled the code, then noticed something confusing looks like ld checks the system old libraries instead of the one comes with devtoolset-6. The LIBRARY_PATH includes the /usr/lib/../lib64/ folder and that causes the error. In any case, If the linker couldn't find these function, it should also check the devtoolset-6 libraries. Looks like this doesn't happen. How could i resolve this linking error?

I try to compile program in C, dedicated for FTDI chip. My enviroment is Advanced Tomato based Asus router + 16GB USB mem stick, mounted as /opt. Additionaly I have compiler + dependences + the newest FTDI library for ARMv7 from FTDI web site.
My compilation command is:
gcc -v -Wl,-rpath=/opt/usr/local/lib -Wl,--dynamic-linker=/opt/lib/ld-linux.so.3 -L/opt/usr/local/lib -O2 -pipe -march=armv7-a -mtune=cortex-a9 -fno-caller-saves -mfloat-abi=soft -l ftd2xx arco.c -o arco
Library patch is:
LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/opt/lib:/opt/usr/lib:/opt/include:/opt/usr/local/lib:/opt/usr/include
Below verbose output from compilation process. Strange think is that in the first part of compilation, location od dynamic linker is correct, that is:
/opt/lib/ld-linux.so.3
But in the second part is wrong, that is:
/lib/ld-linux.so.3
It is not possible to copy/link ld-linux.so.3 to /lib because it is read only filesystem.
All this cause that when I run program, an library error occurs:
./arco: error while loading shared libraries: /opt/usr/local/lib/libftd2xx.so: internal error
Any idea what I am doing wrong?
Compilation output:

I am using Cygwin on 64-bit Windows 8.1.
I wanted to make native windows executables inside the Cygwin environment (i.e. I didn't want to deal with cygwin dll issues). I saw Cygwin had minGW packages so I downloaded the
i686-pc-mingw32-gcc
x86_64-w64-mingw32-gcc
packages. From this post I've gathered the i686 one is 32-bit and the x86_64 one is 64-bit.
I used both the i686 and x86_64 version of g++ to compile a simple hello world program and both compiled without error.
The executable compiled by the i686 works as expected.
My problem: When I try to run the executable compiled by the x86_64 version, I get an windows error box saying "The application was unable to start correctly (0x000007b). Click OK to close the application."
I am very confused by this. Why does the 32-bit compiler work and the 64-bit compiler not work on my system?
In case it helps, here the stuff the x86_64 compiler is doing when I call it
$ x86_64-w64-mingw32-g++ test.cpp -o dd -v

EDIT: Did some more testing. When I made a program more complex than hello world (I used a #include ) the i686 version of the executable failed as it was missing some GCC related dll. When I add -static-libgcc -static-libstdc++, both version of the compilers work.
This leads me to conclude stuffs messed up with my linkers and DLLs. I don't know too much about this :(
I am creating the Embedded Mono Archive for one of my application. As per this link I need to create c/c++ executable which will instantiate appropriate framework and will load my managed assembly into it.
I tried creating the statically linked executable by specifying -static in g++ commandline but did not worked. below is verbose output from my g++ command -
$>g++ -Wall -o monolauncherstatic.out MonoLauncher.cpp `pkg-config --cflags --libs mono-2` -v -static

It seems you don't have static libraries installed, e.g. libc.a, libm.a, libpthread.a, etc.
If you're using SuSE, perhaps yum install glibc-devel-static will work. Maybe some of the other libraries will need other packages to be installed.
My build is failing to link, probably because it's attempting to link against the wrong version of libaries (namely, libssl). The makefile's LIBS directive specifies -lssl, which isn't explicit enough: I have many of these on my system (various system SDKs + newly downloaded version).
My general question is, is there a verbosity option for having make print the explicit paths of the libs used for linking?
Gil.
To see the link step in detail you would usually pass a "verbose" option to the compiler or linker. What system are you using? If gcc, add -v to the compile command. This will produce output like
$ gcc -v hello.c
