Re: [tcljava-user] TclBlend build problems using MSYS on WinNT

[<rja...@nm...>]

That was it.

Downloaded libjvm.dll.a

Did:

LDFLAGS="-L. -ljvm" ./configure ...

and configure ran OK.

Diddled JAVA_LIB_FLAGS in Makefile to match LDFLAGS

and make ran OK.

However having problems with 'make check'.

Dies at # Making test_tclblend.build
in
... javac-g -d /c/TclBlend/tclBlend1.3.0/btests tests/*.java tcl/land/*.java

What signs should I look for now?
