Subject: perl Makefile.PL reports "/usr/bin/dlltool: Can't open def file: jvm.def"
I'm trying to build Inline::Java 0.58 on Cygwin with Perl 5.22. When I run "perl Makefile.PL" part of the output says: /usr/bin/dlltool: Can't open def file: jvm.def Error attempting to create '/cygdrive/c/PROGRA~2/Java/jdk1.8.0_112/lib/libjvm.dll.a' I'm also worried about it saying that it's attempting to write a file to /cygdrive/c/PROGRA~2/Java/jdk1.8.0_112 as that's a protected directory and it won't have permission to write to there (nor should it). Here is the full output: mperry@mperry-PC:~/Inline-Java-0.58$ echo $JAVA_HOME /cygdrive/c/PROGRA~2/Java/jdk1.8.0_112 mperry@mperry-PC:~/Inline-Java-0.58$ perl Makefile.PL Welcome to the Inline::Java installation procedure. Using /cygdrive/c/PROGRA~2/Java/jdk1.8.0_112 as J2SDK directory. Default J2SDK for Inline::Java will be '/cygdrive/c/PROGRA~2/Java/jdk1.8.0_112'. See module documentation for information on how to use a different J2SDK or change this default value. Checking if your kit is complete... Looks good Inline::Java can use a JNI extension that allows the Java Virtual Machine (JVM) to be dynamically linked with Perl instead of running as a separate process. The use of this extension is optional, and building it still allows Inline::Java to run the JVM in the default (separate process) fashion. Note: You need a C compiler to build the extension. Do you wish to build the JNI extension?

I confess to near-total ignorance of the Cygwin platform. Is this still a problem? If so, what happens on "make test"?

Cygwin is a Linux-like environment that runs on Windows. I will do my best to answer any questions you have about it. I retested with Perl 5.24 and Inline::Java 0.65. It still fails with the same errors. I've attached a text file with the output of running "perl Makefile.PL" and "make test". I noticed two issues. 1. "perl Makefile.PL" outputs "/usr/bin/dlltool: Can't open def file: jvm.def". I can't find a jvm.def file. Line 118 of Java/Makefile.PL references that file in a block that's only run on Cygwin. It looks like it was removed in this commit: https://github.com/ingydotnet/Inline-Java/commit/c2a4516ee917814de79643c4019d1b3456cb13ec 2. The same line in Java/Makefile.PL also is attempting to write to the JDK's directory. It fails because the directory is owned by the superuser.

I've figured out what was wrong. I've attached a patch, and I'll send you a pull request on GitHub. I've restored the jvm.def file that was removed. Then I have Makefile.PL create the jvm.dll file in the current directory and link with it during compilation.

(For posterity - Matt figured a way to do without the .def file, which I preferred as more future-proof) Released as 0.66. Thanks!
