I'm following Creating a simple Managed C++ Project -- "Hello World" on a
Windows Platform and Building a simple C++ Project -- "Hello World" on a
Windows Platform. I get the following build output:
make -k clean all
rm -rf ./hello.o ./hello.d HELLO.exe
Building file: ../hello.cpp
Invoking: GCC C++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -ohello.o ../hello.cpp
g++.exe: no input files
make: *** [hello.o] Error 1
make: Target `all' not remade because of errors.
Build complete for project HELLO
What can be wrong?
Thanks/Mikael

Hi,
I ran into the same issue (unable to use MinGW with CDT because of the error
g++.exe: no input files).
Actually it seems to be an issue with make in MinGW (and not with CDT
itself, since the issue can be reproduced from the command line, using
make).
make tries to use 'sh' in order to run the g++ command. (seen using the -d
option, which generates a debug output)
By adding the argument --win32, it was possible to compile:
'Building file: ../JNIAdapter.cpp'
'Invoking: GCC C++ Compiler'
g++ -D_REENTRANT -D_GNU_SOURCE -D__int64="long
long" -I"C:\jdk1.5.0_05\include" -I"C:\jdk1.5.0_05\include\win32" -O3 -Wall
-c -fmessage-length=0 -mno-cygwin -oJNIAdapter.o ../JNIAdapter.cpp
'Finished building: ../JNIAdapter.cpp'
' '
But when make tries to link, it runs again into the same kind of error:
'Building target: ../../PrenzlJ/dll/prenzl.dll'
'Invoking: GCC C++ Linker'
g++ -mno-cygwin -Wl,--add-stdcall-alias -shared -o../../PrenzlJ/dll/prenzl.dll
../JNIAdapter.o
g++.exe: no input files
Running
'g++ -mno-cygwin -Wl,--add-stdcall-alias -shared -o../../PrenzlJ/dll/prenzl.dll
../JNIAdapter.o' from the command line in the same directory actually works.
And that what make seems to do (as can be seen using -d option)
Hope it helps (a little bit), and I would also be grateful for help for the
next step!
I would also be happy to find a MinGW newsgroup. I could not find any. If
anybody knows one...
Cheers,
Mathieu

Hi,
it worked! Thanks a lot!
I used the following install files:
binutils-2.15.91-20040904-1.tar.gz
gcc-core-3.4.2-20040916-1.tar.gz
gcc-g++-3.4.2-20040916-1.tar.gz
gcc-objc-3.4.2-20040916-1.tar.gz
gdb-5.2.1-1.exe
mingw-runtime-3.9.tar.gz
mingw-utils-0.3.tar.gz
mingw32-make-3.80.0-3.exe
w32api-3.5.tar.gz
but not:
MSYS-1.0.10.exe
(as recommanded)
Please note that I had:
+ to rename bin/mingw32-make.exe into bin/make.exe
+ to move some files (from install file gdb-5.2.1-1.exe) from ./mingw32 to .
Cheers,
Mathieu
