Hello! [Please CC: I'm not on the list] [I should have posted here 3 months ago.] I am in the process of porting the ecasound sound processing suite (www.ecasound.org) to FreeBSD (here is 4.2-STABLE). It's really seems to be a fine product, and runs on Linux, for now. :) Ecasound is a command-line tool and a library that is the basis for a few other packages. There is QtEcasound (a Qt GUI) and ecawave (a wave editor that uses QtEcasound libs). For the rest of the hype about ecasound, see the webpage. :) That said, it's very nice and I want it on FreeBSD. :) I have "successfully" ported ecasound-1.8.5d15. The quotes are because there are some things that are _really_ wrong. I get all sorts of warnings when linking the library itself. Ok. Let's go. First, there is the eternal pthread nightmare. I had to patch the configure scripts to make them use '-pthread' and add '-D_THREAD_SAFE' to compilation. Second, I can't find mlockall() on FreeBSD. It's declared in /usr/include/sys/mmap.h (AFAIR). It's supposed to be POSIX.1b. Grepping through /usr/src, I found it in the kernel and some kernel modules, but never in a lib. Anyways: c++ -O2 -D_REENTRANT -DNDEBUG -ffast-math -fstrict-aliasing -funroll-loops -pthread -o ecasound eca-text.o textdebug.o -lncurses -L../libecasound/.libs -lecasound -L../kvutils/.libs -lkvutils -lhistory -lreadline -lc_r -lm ../libecasound/.libs/libecasound.so: warning: tmpnam() possibly used unsafely; consider using mkstemp() /usr/lib/libc.so.4: WARNING! setkey(3) not present in the system! /usr/lib/libc.so.4: warning: this program uses gets(), which is unsafe. /usr/lib/libc.so.4: warning: mktemp() possibly used unsafely; consider using mkstemp() /usr/lib/libc.so.4: WARNING! des_setkey(3) not present in the system! /usr/lib/libc.so.4: WARNING! encrypt(3) not present in the system! /usr/lib/libc.so.4: warning: this program uses f_prealloc(), which is stupid. /usr/lib/libc.so.4: WARNING! des_cipher(3) not present in the system! /usr/lib/libc.so.4: warning: tempnam() possibly used unsafely; consider using mkstemp() ../libecasound/.libs/libecasound.so: undefined reference to `mlockall' So I had to add a "AC_CHECK_FUNCS(mlockall)" and a #ifdef around the call to fix this. (I took this from the mysqld port). Ok. Let's come back on these "libc" warnings. I don't get it. setkey(3) *is* present on my system. It's a plain 4.2-STABLE install, for Knuth's sake! There is not a single occurence of mktemp() or f_prealloc() in ecasound's source!! There is, however, an occurence of gets() in ecasound's readline lib. But I disabled it! For tmpnam(), it *is* used in the code. However, mkstemp() *cannot* be used since tmpnam() is used to generate a name for a *fifo*. mkstemp() creates a file. What do I do with this mess? Anyways, I was able to compile the program, the libs, and all the stuff... That is, I installed the libs in /usr/local/lib and did a ldconfig to refresh that. After that, I tried to compile qtecasound. And there comes the weird part: c++ -lecasound -lkvutils -pthread test.c -o test does not link, but c++ -L/usr/local/lib -lecasound -lkvutils -pthread test.c -o test does. That is, in the first, I get something like: /usr/libexec/elf/ld: cannot find -lecasound But it's there: $ ldconfig -r | grep ecasound 232:-lecasound.7 => /usr/local/lib/libecasound.so.7 254:-lecasoundc.0 => /usr/local/lib/libecasoundc.so.0 $ Yukl. Weird. So that's all i can do for now... Have a nice day! A. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
