I recently compiled the latest version of mod_jk (jakarta-tomcat-3.2.2-src) using the Sun Workshop v6 "cc" compiler on Solaris 8. It found three errors in the mod_jk source code having to do with commenting. Turns out this version of "cc" does not like the double slash comment. To use "cc", you must change the "// ..." comments to "/* ... */" comments in the following files/lines: ./src/native/jk/jk_sockbuf.c - line 227 ./src/native/jk/jk_util.c - lines 217 and 233 I also used the "-lposix4" option as stated in the documentation just in case. You still get warnings when you compile, but the resulting mod_jk.so works with Tomcat 3.2.2 and Apache 1.3.20. Would someone on the development team please make these minor changes in the mod_jk source for us Solaris users? Thank you.
