MAQ install error

Question

[Ashley]

Hello, I've been trying to install Maq onto a 64bit linux system. I've looked at the other threads that have had problems with Maq but nothing in those worked for me so I'm hoping someone might have some new answers! The ./configure step works fine, but when I try to make, I get this output:

(CDPATH="${ZSH_VERSION+.}:" && cd . && autoheader)
rm -f stamp-h1
touch config.h.in
cd . && /bin/bash ./config.status config.h
config.status: creating config.h
config.status: config.h is unchanged
make all-am

make[1]: *** [mapcheck.o] Error 1
make[1]: Leaving directory `/home/jess28/My_Packages/maq-0.7.1'

I've tried doing ./autogen.sh before configuring, but that did not help. I'm have no idea what to do to fix this! Any help would be greatly appreciated.

Why do you need MAQ? Its latest version is more than 10 years old - I think you would be better of using some newer program.

MAQ is really old, and by now it has problems compiling with current compilers. You can use the fpermissive flag to get it to compile:

make CFLAGS="-Wall -m64 -D_FASTMAP -DMAQ_LONGREADS -g -O2 -fpermissive" CXXFLAGS="-Wall -m64 -D_FASTMAP -DMAQ_LONGREADS -g -O2 -fpermissive"

Note I took the CFLAGS and CXXFLAGS from the Makefile, and appended -fpermissive to them. Your CFLAGS and CXXFLAGS may be different, check them before issuing make.
