Hi,

I have now run a build through on windows 10 (x64) using make 4.1 (from EPICS web site), base 3.15.2, seq 2.2.3, strawberry perl 5.22.0 (x64) and visual studio 2015. The sequencer files all compile OK and "make -s runtests" is successful, but I did encountered an error during the build process itself when it failed to generate "snl.bnf" - however after typing "make" a second time everything then runs to completion (the generated "snl.bnf" file is then blank though, but I believe this file is only used to generate documentation)

The build error is:

link -nologo  -debug -incremental:no -fixed:no /MACHINE:X64              -out:snc.exe       lexer.obj snl.obj main.obj node.obj var_types.obj analysis.obj gen_code.obj gen_ss_code.obj gen_tables.obj sym_table.obj builtin.obj type_check.obj     c:/dev/epics-base/lib/windows-x64-debug/Com.lib

operable program or batch file.

make: *** [src.install] Error 2
make: Leaving directory 'C:/dev/seq-2.2.3'

resulting in an empty snl.bnf    I can create a correct snl.bnf by manually running

    ..\..\..\bin\windows-x64-debug\lemon.exe o=. -g ..\snl.lem > ..\O.Common\snl.bnf

from my O.windows-x64-debug directory. If I happen to type instead

    ../../../bin/windows-x64-debug/lemon.exe

I get a " '..' is not recognized " error similar to above, which is a clue to what is happening. The problem seems to be caused by redirecting the output of the lemon command. The relevant Makefile line is:

$(COMMON_DIR)/snl.bnf: snl.lem
	$(LEMON) o=. -g $< > $@

if i remove the "> $@" and just create a blank snl.bnf

$(COMMON_DIR)/snl.bnf: snl.lem
	$(LEMON) o=. -g $<
	@echo > $(COMMON_DIR)/snl.bnf

then the build runs fine. If I use the windows native path instead of $(LEMON) in the original line with output redirection, it is fine too. So it seems that redirecting the output of the lemon command stops correct pathname translation on $(LEMON) prior to passing the command to windows, which I guess is a "make" bug?

Regards,

Freddie
