I've had Eclipse for Java on my computer for a few years, and decided to install the CDT and learn C. I installed both MinGW
and Cygwin
and the CDT detects and tries to use them when I make a new project.
I choose File > New C++ Project
and choose Hello World C++ Project
and the CygwinGCC
toolchain. I name the project "asdf" and hit "Build Debug" in the toolbar. The compiler completes without error. I hit Run and nothing happens.
Browsing to the project directory manually and running asdf.exe gives me an error saying:
"The program can't start because cygwin1.dll is missing from your computer. Try reinstalling the program to fix this problem."
The same thing happens using MinGW, only a different dll is missing.
What do I need to do to have a usable .exe?
(I'm running Windows 7 x64 and the newest version of Eclipse and the CDT.)
EDIT: The compiler output is as follows:
**** Build of configuration Debug for project asdf ****
make all
Building file: ../src/asdf.cpp
Invoking: Cygwin C++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/asdf.d" -MT"src/asdf.d" -o"src/asdf.o" "../src/asdf.cpp"
cygwin warning:
MS-DOS style path detected: C:\Users\Shawn\Dropbox\eclipse\asdf\Debug
Preferred POSIX equivalent is: /cygdrive/c/Users/Shawn/Dropbox/eclipse/asdf/Debug
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:

You can compile with either Cygwin's g++
or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll
(and others) PATH to the system Windows PATH, before any cygwin style paths.
Thus add: ;C:\cygwin64\bin
to the end of your Windows system PATH
variable.
Also, to compile for use in CMD or PowerShell, you may need to use:
x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe
(This invokes the cross-compiler, if installed.)
