I followed your suggestion; installed strace and reran the revised command line. The output can be referenced at http://pastebin.com/m7cb292d5 The definitive line is: 172. [pid 6423] access("/usr/local/share/java/ecj.jar", F_OK) = -1 ENOENT (No such file or directory) See also lines 81,82 and 85. Basically, the problem is that compiler was looking for ecj.jar under a fixed(?) /usr/local/share path instead of the path where I had custom installed: /usr/local/gcj; moreover it should have been looking under the full path of /usr/local/gcj/usr/local/share/java. To work-around the path problem, I copied the java directory and its contents (on my server, there was no java directory under /usr/share) as in the following: plug local # pwd /usr/local/gcj/usr/local plug local # ls share/java ecj.jar libgcj-4.5.0.jar libgcj-tools-4.5.0.jar plug local # cp share/java/* /usr/local/share/java plug local # plug local # strace -f -etrace=file bin/gcj -c /var/work/gcj/HelloWorld.java plug local # plug local # ls bin HelloWorld.o include lib libexec share plug local # My successful run is posted at http://pastebin.com/m74e42dc9 I have Bug 42409 pending and will update it with attachments and this conclusion. Thank you, Andrew. - John L. Poole
