automake “permissions denied”

Question

i want to compile changes i made to a project created with automake.

I changed my Makefile.am files accordingly and ran

./autogen.sh
./configure
make

make finally gives me the error:

...
make[2]: Betrete Verzeichnis '/home/dino/workspace/ba/sharp-1.0/src'
/bin/bash ../libtool  --tag=CXX   --mode=compile g++ -DHAVE_CONFIG_H -I. -I..  -      I../include -I../include/sharp -ansi --pedantic-error -Wall   -g -O2 -MT Global.lo -MD -   MP -MF .deps/Global.Tpo -c -o Global.lo `test -f './Global.cpp' || echo './'`./Global.cpp
../libtool: line 2090: ./Global.cpp: Permission denied
libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I.. -I../include -I../include/sharp -ansi     --pedantic-error -Wall -g -O2 -MT Global.lo -MD -MP -MF .deps/Global.Tpo -c ""  -fPIC -  DPIC -o .libs/Global.o
g++: error: : No such file or directory
g++: fatal error: no input files
compilation terminated.

The command above doesn't work on any source file. So i imagined it could only be my automake that broke the project.

Answer 1

Whenever I come across an issue like this, its due to not using the sudo prefix.

sudo ./autogen.sh
sudo ./configure.sh
sudo make

What the problem is you as a user don't have permission to use whatever file is required, and the make process is cancelled. Executing as sudo solves the issue.
