Failing to install omentpp 4.1
compiler-errors, omnet++
Solution
Edit the file `src/utils/abspath.cc` and manually add the following:
#include <unistd.h>
Save and compile again. Problem solved.
Problem
I am trying to install omnetpp 4.1 (can't install the new version). Anyway, running `./configure` reports no errors or warnings, but when I run `make` I get the following: ``` make MODE=release make[1]: Entering directory `/home/yotam/omnetpp-4.1' ***** Configuration: MODE=release, TOOLCHAIN_NAME=gcc, LIB_SUFFIX=.so **** ===== Checking environment ===== mkdir -p /home/yotam/omnetpp-4.1/bin ===== Compiling utils ==== cd /home/yotam/omnetpp-4.1/src/utils && make make[2]: Entering directory `/home/yotam/omnetpp-4.1/src/utils' g++ abspath.cc -o /home/yotam/omnetpp-4.1/out/gcc-release/src/utils/abspath abspath.cc: In function ‘std::string toAbsolutePath(const char*)’: abspath.cc:62:38: error: ‘getcwd’ was not declared in this scope make[2]: *** [/home/yotam/omnetpp-4.1/out/gcc-release/src/utils/abspath] Error 1 make[2]: Leaving directory `/home/yotam/omnetpp-4.1/src/utils' make[1]: *** [utils] Error 2 make[1]: Leaving directory `/home/yotam/omnetpp-4.1' make: *** [allmodes] Error 2 ``` I am running ununtu 12.10 if it matters. Seems to be code errors, right? Any suggestions? Thanks
