For me configure does not detect sparsehash-2.0.3 not even with current git master at commit af73db6 :

Thanks @mmokrejs for the detailed report.

Do you remember how you configured your installation of sparsehash? It should not be looking for std::hash and should have no problems compiling with -std=c++98. I see you've reported a very similar issue here: bcgsc/abyss#225. Was this ever resolved?

It was built with gcc-8.2.0 or 8.3.0. No special CFLAGS/CXXFLAGS fiddling with -std or similar.

No, the issue in abyss was not solved.

Thanks. I don't see anything there would cause a problem. Can you paste the contents of your sparsehash/internal/sparseconfig.h file?

Ok, that confirms your sparsehash is configured to assume c++11 hash functions are available.

I am reluctant to change the dialect to c++11 just over this issue. SGA is no longer used for assembly very often but some subprograms it contains are still useful. Perhaps I should default to using the standard hash map if sparsehash is unavailable instead of dying.

FWIW, I was able to compile with c++11 with the following changes:

configure.ac
AC_SUBST(CXXFLAGS, "-std=c++11 -O3")

ClusterReader.cpp
bool good = static_cast<bool>(getline(*m_pReader, line));

rmdup.cpp
bool valid = static_cast<bool>(getline(*reader_vec[currReaderIdx], line));
