Public bug reported: Compilation of QEMU fails when using recent versions of zstd.
I use the following commands to compile QEMU: $ mkdir build $ cd build $ ../configure --enable-debug --target-list=x86_64-softmmu $ make -j $(nproc) Here is a paste from the ../configure output: https://paste.ubuntu.com/p/dHsWzGV7TH/ And one from the make output: https://paste.ubuntu.com/p/89qKk4NrFz/ In short the error boils down to: ../block/qcow2-threads.c: In function ‘qcow2_zstd_compress’: ../block/qcow2-threads.c:225:16: error: implicit declaration of function ‘ZSTD_compressStream2’; did you mean ‘ZSTD_compressStream’?
