What is this error
:!make
g++ -g -I../direc1 -I./ -c final.cpp
make: g++: Command not found
make: *** [final.o] Error 127
?
You don't have g++ installed (or it's not in your $PATH variable).
The error message says it all.
You don't have g++ installed or
You have it installed but it is not in your PATH environment variable.
g++ not found indicates that your system can not find the executable file g++.
Ensure that your system knows where to search for g++.
On windows, this is done via the environment variable "path".
Add the g++ path in $PATH export PATH=$PATH:g++Path

I have encountered a problem after setting the path of boost libraries in Eclipse. I get an error like:
No such file or directory
compilation terminated.
Here is my log:
15:32:06 **** Rebuild of configuration Debug for project Demo ****
Info: Internal Builder is used for build
g++ "-IC:\\boost\\boost_1_66_0" "-includeC:\\boost_1_66_0" -O0 -g3 -Wall -c -fmessage-length=0 -o "src\\Demo.o" "..\\src\\Demo.cpp"
cc1plus: fatal error: C:\boost_1_66_0: No such file or directory
compilation terminated.
15:32:06 Build Finished. 0 errors, 0 warnings. (took 147ms)
Looks like your paths aren’t aligned for the -l flag and the -include flag. It should be “-includeC:\boost\boost_1_66_0”, or the correct path to the boost root directory.
See this boost doc for more info.
I am new to Linux environments, and trying to install a bioinformatics package (vcftools - https://vcftools.github.io/examples.html). For some reason I can compile without a problem in a Cygwin environment, other colleagues have installed the package without a glitch, but i get an error (per below) if I try to compile in an Ubuntu environment in a VirtualBox on the same computer. I get the following error. Does anyone have a suggestion on how to resolve this error?
$make install

error with make
Basically what the makefile does is automating the calls to the compiler.
Thus, the output from the makefile is similar to usual compile errors you get, compiling a source file from within the command line.
The important line from the error log above is:
vcf_file.cpp: In constructor ‘vcf_file::vcf_file()’:
**vcf_file.cpp:25:13: **error: cannot convert ‘bool’** to ‘gzFile {aka gzFile_s*}’ in assignment**
gzvcf_in = false;
gzvcf_in is of type pointer to gzFile_s. Assigning a bool variable to a pointer type won't compile.
Thus, the error message. Replace, inside the vcf_file.cpp, false with the pointer literal std::nullptr or the macro NULL and re-run the makefile.
Btw. I checked the vcf_file.cpp file in the github repo from vcf. They do not contain the line leading to the above error. May you have an outdated / modified version, introducing the compiler error.
I see that this issue has been posted many many times but none of solutions worked for me and my problem is a bit different.
The problem:
When a use a makefile and mingw32-make, I get the error:
g++: error: CreateProcess: No such file or directory
However, if I copy/paste the SAME command that the makefile tried to do and paste it in the SAME command prompt it works. This problem only occurs when I try to build with a makefile.
Here's more info:
g++ ./src/main.cpp ./src/application.cpp -I C:\Code\infographie\Labs\inc -L C:\Code\infographie\Labs\lib -I C:\Code\infographie\Labs\inc -g -Dmain=SDL_main -L C:\Code\infographie\Labs\lib -lmingw32 -lSDL2main -lSDL2 -o bin/debug/labs.exe
g++: error: CreateProcess: No such file or directory
makefile:23: recipe for target 'all' failed
mingw32-make: *** [all] Error 1
As I said, If I copy/paste the first line it will work.
What can I try?
UPDATE: I've installed cygwin, adjusted SDL libs and recompiled. Now I get this error when I try to use make. If I copy/paste the command, it works.
g++ ./src/main.cpp ./src/application.cpp -I C:\Code\infographie\Labs\inc -L C:\Code\infographie\Labs\lib -I C:\Code\infographie\Labs\inc -g -Dmain=SDL_main -L C:\Code\infographie\Labs\lib -lcygwin -lSDL2main -lSDL2 - mwindows -o bin/debug/labs.exe

FIXED IT, don't declare a variable named PATH...
Stop using MinGW.
MinGW has not been updated since 2013. It has been replaced by Cygwin and
MSYS2. The MinGW project doesn’t even offer a 64-bit compiler.
Cygwin can be installed in about 3 minutes, I would give it a try.
ok so i installed CDT for C++ development on my machine. I tried to make it work and followed these instructions to set everything up. By mistake i have gone into the Project>Properties>C++ Build>Enviorement and hit restore defaults by mistake. I dont know if that changed anything but i get the following error when i run my class.
I tried to switch the slashes in the given path "C:\Users\Nathan\workspace\Project\Debug" to forward slashes but that did nothing. I still get the same error. Any hints on what im doing wrong?

I'm trying to compile Festival on MingW32, so I can have a Windows binary. I couldn't find the Windows binary on their site. Anyone have one they can post?
If not, here's what I have so far. I did the ./configure and make for it and have the following message:
$ make
config/config:43: ../speech_tools/config/config: No such file or directory
So, I downloaded the speech_tools tar ball and got. Did the ./configure and make to get:
$ make
config/config:156: config/systems/ix86_unknown.mak: No such file or directory
../config/config:156: ../config/systems/ix86_unknown.mak: No such file or directory
make: *** No rule to make target `../config/systems/ix86_unknown.mak'. Stop.

make[1]: *** No rule to make target `../config/systems/ix86_unknown.mak'. Stop.
make: *** [config/modincludes.inc] Error 2
So, I copied config/systems/ix86_CYGWIN32.mak to ix86_unknown.mak and tried again. Now I get this message:

Where do I get sys/wait.h, sys/resource.h and strstream.h? I'd rather not have to try this whole bit in Cygwin and carry around those annoying DLL's. Any advice?
Windows binaries are available here
You'll get further with a full cygwin install instead of just mingwin, but I can't promise success.
I run Ubuntu and remember having Festival available in the Synaptics repository, implying I just had to double click the name, and the thing installed itself with all its dependencies.
If all else fails, you might want to run a VM with ubuntu or dual boot.
