[Gate-users] error install lmf

[David Boersma]

Dear Yuan Bo,

The LMF code is very old and is incompatible with modern compilers. But if you tell the compiler that it should use an old standard, then you will not get these errors. You can do this by adding "-std=c99" to the compiler flags for for *.c files, and "-std=c++98" for *.cc files. Lines 30-37 of the makefile would then look like this:

obj/%.o : src/%.c
        gcc $(CFLAGS) -std=c99 -c -o $@ $<

obj/outputRootMgr.o : src/outputRootMgr.cc
        gcc $(CFLAGS) $(ROOTCFLAGS) -std=c++98 -c -o $@ $<

obj/%.o : src/%.cc
        gcc $(CFLAGS) -std=c++98 -c -o $@ $<

(Our mail programs are probably distorting the layout of this text. Please make sure that lines with "obj" are starting at the very beginning of the line, and lines starting with "gcc" should start with a TAB, and definitely not with normal spaces. Yes, the "make" grammar is a bit peculiar.)

With ROOT 5 and gcc version 7.3.0 this compiles on my machine. I did not try any other versions.

I hope that this helps you a little bit. Note that all this comes with VERY BIG DISCLAIMERS: I am not at all an LMF expert, and even though we provide the lmf tarball on our website, we do not officially support this. So I am not guaranteeing anything about whether the above will work. And even if it compiles, it may still run incorrectly: I did not test it... :-)

Good luck,
David Boersma
