Did you build desktop or on that same dir? If so, you need to clean it as it doesn't use multiple instances. enohp ym morf tnes ----------- Dan Wilcox danomatika.com robotcowboy.com On May 31, 2025, at 4:16 PM, Alexandros Drymonitis <[email protected]> wrote: On 5/31/25 14:50, Miller Puckette wrote: I've been trying to figure out how that could happen without success. libpd should be defining the missing symbol (s_signal). This is a shot int he dark but can you try "nm libpd.a" from the .../pd/libpd directory? I get this: sp@bang:~/pd/libpd$ nm libpd.a |grep s_sig 00000000000000a0 D s_signal I get the following: ``` U s_signal U s_signal U s_signal U s_signal ``` so I guess the symbol is missing. I tried deleting everything in the libpd directory (apart from the Makefile, README and the test_libpd directory) and to re-build it with `make MORECFLAGS=-DVST_CLEANSER MORESRC=[...path-to...]/PureVST/source/vst_cleanser.c` but the result is the same ... so libpd.a is defining the (apparently missing) symbol. If yours is missing, then somehow the libpd.a build missed including vst_cleanser.c from the pureVST source. But if yours is present like mine is (which I expect you to find) then something about the linker command is funny. You could then run "cmake --build . --verbose" so that we could both look at how the linker is getting invoked on our respective systems. Meanwihle... in trying to recompile everything from scratch I now get a problem further down the line (a segfault trying to run Steinberg's 'validator'.) I had to start all over and add -DSMTG_RUN_VST_VALIDATOR=FALSE to the cmake command - then, unexpectedly, I was able to load the plugin under ardour and all seemed fine. But something seems to be pretty fragile here :) Miller On 5/30/25 3:16 PM, Alexandros Drymonitis wrote: Replying to list.

I created a build directory and changed to that. I also corrected the paths to the VST3 SDK and Pd's source (well, Pd's directory that includes the src/ directory, not the actual src/ directory; that's what I got I should do from the CMakeLists.txt file) and I run: `cmake -DCMAKE_BUILD_TYPE=Release` but I got the following error: ``` CMake Warning: No source or binary directory provided. Both will be assumed to be the same as the current working directory, but note that this warning will become a fatal error in future CMake releases. CMake Error: The source directory "/home/alex/Applications/puredata/PureVST-0.5/build" does not appear to contain CMakeLists.txt. Specify --help for usage, or press the help button on the CMake GUI. ``` Perhaps something is missing in the command, like a double dot? I know nothing about CMake, so this could be rather trivial...

If you've downloaded and unpacked the PureVST source tarball it should be just "purevst/source/vst_cleanser.c". And yes, no trailing period (I think my markdown-to-html converter remove the space I had put between the filename and the period). and yes, 'wherever the sources landed" refers to the pureVST source (currently https://msp.ucsd.edu/tools/purevst/PureVST-0.5.src.tgz ) whic need dwonloading and unpacking before even making this version of libpd. cheers Miller On 5/30/25 8:39 AM, Alexandros Drymonitis wrote: I'm trying to compile pureVST from source on Debian 12. I built the VST SDK and following pureVST's README, I've gone up to the following step `make MORECFLAGS=-DVST_CLEANSER` insinde the libpd directory. I don't quite understand the following steps. Right after this, the README reads that I should type `MORESRC=../../work/vst/purevst/source/vst_cleanser.c.` Being inside the libpd directory, where will the two parent directories lead me, since the path starts with ../../? Also, where is this `work` directory supposed to be? Or `vst` and `purevst`? Are these directories Miller created in his system? I did a `find . -name vst_cleanser.c` from my home directory and found nothing (BTW, is the dot at the end supposed to be there?). Then the instructions follow like this: ``` Then using the PureVST source tree, consult the CMakeLists.txt file and correct the path settings for the VST SDK and for the Pd source. Then make an empty build directory, and using a shell or terminal window, change directory to the build directory and try to get these to work in sequence: |SRC=~/work/vst/purevst| [… or wherever the sources landed] |cmake -DCMAKE_BUILD_TYPE=Release -DSMTG_ENABLE_VST3_PLUGIN_EXAMPLES=FALSE -DSMTG_ENABLE_VST3_HOSTING_EXAMPLES=FALSE -DHOME=$HOME $SRC| |cmake --build .| ``` It mentions "or wherever the sources landed". Which sources? After building libpd? And in which directory should all the cmake command be executed? --- [email protected] - the Pure Data mailinglist https://urldefense.com/v3/__https://lists.iem.at/hyperkitty/list/[email protected]/message/G6WKC35RKLRYGKG6SBU7XNVVJJMAKKZO/__;!!Mih3wA!DFen_RjYHJNb45mR5Hyg6bFkcnp_5FiD-L8x3J77DDNf8kSeESnTcAvpifvoHQuLXlMtgG3c4g$ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://urldefense.com/v3/__https://lists.iem.at/__;!!Mih3wA!DFen_RjYHJNb45mR5Hyg6bFkcnp_5FiD-L8x3J77DDNf8kSeESnTcAvpifvoHQuLXlNkw1GM2g$ --- [email protected] - the Pure Data mailinglist https://urldefense.com/v3/__https://lists.iem.at/hyperkitty/list/[email protected]/message/TNRUNARSDQYEJRVRR7YXBKGVMEWZ5LSK/__;!!Mih3wA!EURYqzxhS_He9z-6PE0AFFJAE3XlM9Nxhvdcr9dGcpyw1ylz7W38fLqzqve9fW5vcKYm61iPow$ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://urldefense.com/v3/__https://lists.iem.at/__;!!Mih3wA!EURYqzxhS_He9z-6PE0AFFJAE3XlM9Nxhvdcr9dGcpyw1ylz7W38fLqzqve9fW5vcKYH7gGC2w$ --- [email protected] - the Pure Data mailinglist https://urldefense.com/v3/__https://lists.iem.at/hyperkitty/list/[email protected]/message/TIRTMUGDE6MPPDG5JDZGATYQXCP5CXVB/__;!!Mih3wA!EURYqzxhS_He9z-6PE0AFFJAE3XlM9Nxhvdcr9dGcpyw1ylz7W38fLqzqve9fW5vcKYL9pcD7g$ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://urldefense.com/v3/__https://lists.iem.at/__;!!Mih3wA!EURYqzxhS_He9z-6PE0AFFJAE3XlM9Nxhvdcr9dGcpyw1ylz7W38fLqzqve9fW5vcKYH7gGC2w$ --- [email protected] - the Pure Data mailinglist https://urldefense.com/v3/__https://lists.iem.at/hyperkitty/list/[email protected]/message/II7K4ZFPH6QF4PYJ5MZJJ6PUSWZYBN62/__;!!Mih3wA!H13gOLNhjW0b3yIv3Mv32sdTdhORLrti5ptp8icO2d2-axGPFy0ONnZkiXgjTBRwNGWSwTaEgw$ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://urldefense.com/v3/__https://lists.iem.at/__;!!Mih3wA!H13gOLNhjW0b3yIv3Mv32sdTdhORLrti5ptp8icO2d2-axGPFy0ONnZkiXgjTBRwNGXCIV33JQ$ --- [email protected] - the Pure Data mailinglist https://lists.iem.at/hyperkitty/list/[email protected]/message/ONACOAA2TPVCFNFLSXB6TSZA7QH5KZE6/ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://lists.iem.at/ --- [email protected] - the Pure Data mailinglist https://lists.iem.at/hyperkitty/list/[email protected]/message/GULRESQ4SGXXOJ5AGZAK64T74QCFWWWM/ To unsubscribe send an email to [email protected] mailing list UNSUBSCRIBE and account-management -> https://lists.iem.at/
