Summary0000332: Cannot find symbols in lpiUtil.jar
Description#Problem: compiling formalLang_lib.m with ../lpiUtil/lpiUtil.m in the JAVA grade.

# formalLang.m, a wrapper around formalLang_lib.m, and lpiUtil.m is working fine.
# We have a similar Makefile for building mercury code-- working immediately below:
#formalLang 548>./formalLang aabb
#A^nB^n --> aabb
#formalLang 548>./formalLang aab
#Failed to parse input sentence.

# We need to tell javac about the Mercury libraries.
UTILPATH = ../lpiUtil
#lpiUtil 527>mmc --make -s java liblpiUtil
# creates
# lpiUtil.jar

See steps below to reproduce.
Thanks for your time.
Steps To ReproducePart of a larger makefile: Makefile_formalLang_lib_jar (see attached).

    --link-object ../lpiUtil/liblpiUtil.a \
    --init-file ../lpiUtil/lpiUtil.init

 The error is because the Java compiler cannot find lpiUtil. You may need to use the mmc --java-classpath option. Use mmc -v to see the actual javac command.

I don't understand why you are trying to link with a .a file, which (normally) contains native code.

 You were correct, --java-classpath $CLASSPATH and -v option solved the problem; no need for
native code (.a).
Thanks; working code below:
formalLang 507>make -f Makefile_formalLang_lib_jar
...

formalLang 507>./mercury_main
In Mercury main, about to call java_main...
In java_main()...
abc, one_parse() gives value = A^nB^nC^n --> abc
ab, one_parse() gives value = A^nB^n --> ab
b, one_parse() gives value = Failed to parse input sentence.
a, one_parse() gives value = Failed to parse input sentence.
aabb, one_parse() gives value = A^nB^n --> aabb
aaabb, one_parse() gives value = Failed to parse input sentence.
aaaabbb, one_parse() gives value = Failed to parse input sentence.
aaabbb, one_parse() gives value = A^nB^n --> aaabbb
aaabb, one_parse() gives value = Failed to parse input sentence.
Returning from java_main()
Back in Mercury main.
