Compilation problem

[karel-brinda]

Hello, I have the following problem with compilation. SDSL is already compiled in ../sdsl-lite. Do you have any idea how to fix it? Thanks.

karel@optikarel:~/github/bwt-merge$ make SDSL_DIR=../sdsl-lite/ VERBOSE=1
/usr/bin/c++ -std=c++11 -Wall -Wextra -DNDEBUG   -DVERBOSE_STATUS_INFO -pthread -O3 -ffast-math -funroll-loops -msse4.2 -DHAVE_CXA_DEMANGLE -I/usr/local/include -c bwt.cpp

It looks like you don't have the SDSL header files installed in /usr/local/include, which is the include directory set in your $(SDSL_DIR)/Make.helper. Try rerunning the SDSL install script.

I am sorry, I didn't know that it requires a full installation of SDSL. In such a case, it is a problem for me because on most of machines I use, I don't have root.

If you don't specify the install directory for install.sh, it installs SDSL into your home directory and updates Make.helper accordingly.

Thanks, it works now. Btw. would not be possible to use $(SDSL_DIR) for everything?

The SDSL convention is to use the compilers, options, and directories specified in Make.helper.
