I am new to SDL I recently tried to run a SDL program on my Fedora machine and when I try to compile my program using the following command:
gcc -o displayimg displayimg.c -lSDL
I am getting the following error:
/var/bin/ld: cannot find LSDL
collect2: error: ld returned 1 exit status
I have used the SDL2/SDL.h header as well. Any help would be appreciated. I am on Fedora 24.
I figured it out. I was linking
-LSDL
instead of:
-LSD2
I followed this thread to help me out:
How to install SDL2 library in Fedora 20

I'm sucessfully building pulp-riscv-gnu-toolchain from this this
But when I try to compile my simple source code with builded compiler,
error occured.
My command is riscv32-unknown-elf-g++ -o hello hello.cpp
Error message is /home/jskim/test_toolchains_lib/gcc/riscv32-unknown-elf/7.1.1/../../../../riscv32-unknown-elf/bin/ld : cannot open linker script file riscv.ld : No such file or directory
So I try with this command riscv32-unknown-elf-g++ -o main main.cpp -T /home/jskim/test_toolchains/riscv32-unknown-elf-ld/lib/ldscripts/elf32lriscv.x
But following error occured : /home/jskim/test_toolchains/lib/gcc/riscv32-unknown-elf/7.1.1/../../../../riscv32-unknown-elf/lib/crt0.o: In function '.L0': (.text+0x10):undefined reference to '_fbss' collect2: error: ld returned 1 exit status
I'm using CentOS 7.6 and I try build this pulp-gcc with gcc 4.8.5 and 7.3.1 but both shows me same error. Please help me.
I resolve the problem in this way.
Actually Here is the solution.
I'm not accurate but I think the problem is that the name is not matched.
crt0, which seems to be the helper of start riscv processor has this line la a0 _fbss just basically linker can recognize this if _fbss is replaced with _edata. So i edit the assembly file which is located at pulp-riscv-gnu-toolchain/riscv-newlib/libgloss/riscv/ And rebuild the gnu toolchain. And execute your compiler with -T option like riscv32-unknown-elf-g++ -o main main.cpp -T /home/jskim/test_toolchains/riscv32-unknown-elf-ld/lib/ldscripts/elf32lriscv.x
This is the easiest solution as I think.
I've mainly worked on Windows, so I'm quite unfamiliar with less common issues under Linux.
Here's the error I'm getting when dub tries to link my application:
/usr/bin/ld: .dub/obj/pixelperfectengine_pixelperfecteditor.o: undefined reference to symbol 'inflateEnd'
//lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Error: /usr/bin/gcc failed with status: 1
/usr/bin/ldc2 failed with exit code 1.
I've an image handling library as a dependency, which is required for the application, and it (obviously) uses zlib for *.png compression/decompression. I've installed zlib1g-dev for Ubuntu, but did not fix my issues, and the same exact code compiles without any issues under Windows.
You need to link in zlib, as mentioned before.
I would recommend to do so via the "libs" array (see this page: https://dub.pm/package-format-json.html). The advantage of using libs over lflags is that libs will try to use pkg-config, which is a generic way to get linker / compile flags for C[++] libraries on POSIX. It works on Linux and Mac OSX. If pkg-config is not found, dub will just default to do what lflags would do in the first place.
Here's an example from my own project: https://github.com/Geod24/libsodiumd/blob/9b397645e2fc3ca502acb58e1b4631d3faf094e2/dub.json
/lib/x86_64-linux-gnu/libz.so.1: error adding symbols: DSO missing from command line
This error is telling you that you must add -lz to command line. I don't know what dub is, but somehow you must convince it to add -lz to the link command it constructs.
It's probably enough to add -lz to the lflags in your dub file.
I have installed QT5 that also comes with QT creator on an amd machine running ubuntu 12.04. My grapics driver is a radeon r9270x if that matters.
When I try to compile a basic "hello world" type Qt program I get the error message "cannot find -lGL". I have searched around and here( Qt: can't find -lGL error ) it says to use "sudo apt-get install libgl1-mesa-dev" but when I do I already have that installed. Here ( Installing Qt on linux, cannot find -lGL ) it says to install "sudo apt-get install libgl-dev" but that only gets me
"Reading package lists... Done Building dependency tree Reading
state information... Done Package libgl-dev is a virtual package

install.
E: Package 'libgl-dev' has no installation candidate"
Various other resources that I have used say to do similar things but I get this error still. Any ideas?
As a side not, not knowing the relevance, I could not get QT creator to launch for the longest time. It would always seg fault and core dump. I finally updated my amd catylist control center/video drivers and that fixed the problem.
Here is the compile output from qt creator:

Try running this, restart Qt creator and try a clean build.
sudo apt-get install mesa-common-dev
EDIT:
Could be that you just miss Mesa package. Take a look at XCB dependencies listed here and install what’s missing.
I’ve seen this error also mentioned in a different case, but I don’t remember the solution there. I think I had solved the problem by installing the “libglu1-mesa-dev” package.
sudo apt-get install libglu1-mesa-dev -y
But I am not entirely sure if just this had fixed the issue or I had to install anything else.
So what I found worked for me, I manual added the path to the library and compiled. Then I was able to remove the manually added path. I assume somewhere on the backend it was not searching the correct place and once it was shown it remembered and kept the correct location.
I am trying to build a project written in c++ on Linux Mint 16, using...
make -f ./Makefile
and I keep getting this error
/usr/bin/ld: cannot find -ludev
collect2: error: ld returned 1 exit status
make: *** [BINARY] Error 1
I was getting a lot more of the /usr/bin/ld: cannot find -foo, but I checked in my Makefile and, using the synaptic package manager, installed all the other necessary libraries, eliminating all but this error. I cant seem to find it anywhere, although perhaps I am not looking in the right places.
Thanks.
I had the some problem, right after updating to Linux Mint 17.1. I was trying to build an application with Qt 5 serial port module. Solved by installing: libudev-dev .
try:
sudo apt-get install udev
I don't know how to do that in synaptic, but it should be easier, right?
Here's my situation. I'm trying to package a game for Linux (on Ubuntu 13.04) written in Python 3.3 via cx_Freeze. Fine. I installed it via sudo apt-get install cx-freeze. Even though it installed, it didn't show up. So it's the Python 2 version. Fine. I then downloaded the source code from the website and tried to compile it with python3 ./setup.py build. This is where things fall apart. I get this error from the compiler:
/usr/bin/ld: cannot find -lpython3.3
collect2: error: ld returned 1 exit status
error: command 'gcc' failed with exit status 1
I'm using Python 3.3.2, which I compiled from source. Any tips?
Reposting as an answer:
In general, I'd recommend using the Python packages from your distribution, which are already compiled in a way that cx_Freeze can work with. In Ubuntu, you can install python3 and python3-dev.
If you need to compile your own Python interpreter, then you'll need to compile it with a shared library, like this:
./configure --enable-shared
There are more instructions on compiling in the CPython devguide.
