Im trying to compile something in Ubuntu 14.04 and get this error message while libboost package is already installed.
/usr/bin/ld: cannot find -lboost_system
/usr/bin/ld: cannot find -lboost_filesystem
/usr/bin/ld: cannot find -lboost_program_options
/usr/bin/ld: cannot find -lboost_thread
collect2: error: ld returned 1 exit status
I hope somebody can help me fast to resolve this error.
Many thanks!
You need to install libboost-all-dev package.

When I try to build a new project using Qt Creator, I get these errors:
/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libQtGui.so when searching for -lQtGui
/usr/bin/ld: cannot find -lQtGui
/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libQtCore.so when searching for -lQtCore

/usr/bin/ld: skipping incompatible /usr/lib/x86_64-linux-gnu/libpthread.a when searching for -lpthread
collect2: error: ld returned 1 exit status
make: *** [untitled] Error 1
This is the command line from Compile Output:
g++ -m32 -o untitled main.o mainwindow.o moc_mainwindow.o -L/usr/lib/x86_64-linux-gnu -lQtGui -lQtCore -lpthread
It seems it is trying to build in 32-bit mode even though I'm on Ubuntu 64-bit.
I found the problem - my Qt Kits were all wrong. I had reinstalled Ubuntu recently, switching from 32-bit to 64-bit, but I had preserved my home folder, and I had a stale configuration at ~/.config/QtProject/. Deleting that folder fixed my problem and now Qt Creator builds projects fine.
I am using xubuntu 16.04 amd64, and use the D Language. I used to use DMD i386 on a 32 bit machine (ubuntu 14.04), but now, for some reason, I can't (or don't want to) install DMD_i386 on my system, so I installed the one for amd64. All of my projects were written on a 32 bit machine, and I used the int type instead of the long type that's available on 64bit. Now whenever I try to compile something that I wrote earlier, that looks something like this, gives an error;
void someFunction(){
string[] someArray;
uint ln = someArray.length;//This compiled perfectly on 32 bit, but now it says that someArray.length is ulong, and ln is uint.
}
I know that changing ln's type to ulong will fx it, but I wan't to compile this for 32 bit, and not 64 bit, and on 32 bit, the long/ulong type isn't available, since it uses 64 bits.
What I've tried:
I've tried using the -m32 switch to make DMD produce 32 bit output. The error mentioned above is fixed by this, but a linker (ld) error shows up:
/usr/bin/ld: cannot find crt1.o: No such file or directory

How do I get DMD to produce 32 bit output on a 64 bit DMD?
Solved the problem myself. Turns out, I was missing some packages needed by the linker. This solved the problem:
sudo apt install gcc-multilib
I'm trying to install caffe in Ubuntu 15.04, but get stuck in the make execution. Here is my command and the results. Can anybody help me out?

It seems like cuDNN is not installed in your system.
Try commenting out the line USE_CUDNN := 1 in Makefile.config. Do a make clean and build the project again.
I'm running Ubuntu 12.10 (64-bit), with Linux kernel 3.5.0-51-generic, on an AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ ×2. I have GNU Fortran (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2.
I'm trying to compile some code into a 32-bit executable. I've checked that all the needed libraries are installed on my system (I ran ldd on a program previously compiled on a 32-bit computer, and downloaded the missing packages). I tried running $ gfortran foo.f -m32 -L/lib/i386-linux-gnu, but I get the following errors:

I checked the /usr/lib/gcc/i686-linux-gnu/4.7 and /usr/lib/gcc/i686-linux-gnu/4.7.2 directories, and they are both empty.
Can you please help me solve this problem? I did my research but this was as far as I could get.
Thank you in advance!
The 64-bit libraries /usr/lib/gcc/x86_64-linux-gnu/... don't apply to your 32-bit compile. You need to install the multilib compiler packages (see https://help.ubuntu.com/community/InstallingCompilers). For example:
sudo apt-get install gfortran-multilib
Now gfortran -m32 foo.f should work.
I'm trying to compile a 32 bit assembly code(NASM) on my 64 bit Linux, but I can't, I have tried others tutorials about it and I installed ia32-libs...
When I try run it as:
gcc asm1.o -o asm1
i386 of the file input `asm1.o' is incompatible with the output i386:x86-64
And when I try run it as:
gcc -m32 asm1.o -o asm1
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: connot find -lgcc_s
collect2: error: ld returned 1 exit status
Thanks for helps.
OBS: Sorry for my english, I'm not from US.
Need to install gcc-multilib.
