Hi, I am trying to build libraw 0.20.2 on ubuntu 18.04. Running ./configure results in this error

./configure: line 16405: syntax error near unexpected token `ZLIB,zlib,'
./configure: line 16405: ` PKG_CHECK_MODULES(ZLIB,zlib,'

Anyone have experience with this?

Thanks,
Tom

we was using "dcraw.exe" to run the Canon 7D's cr2 file, the command are: -W -D -4.
Right now we used "dcraw_emu.exe" to run the Canon 90D's cr3 file,but we cannot got the same command like -W -D -4 (there is no -D "-D Document mode without scaling (totally raw)").
Could you let me know how can we get the same command -W -D -4 with the Canon 90D's cr3 file ?

Is there a way to tell if a Fuji RAF file is using lossy compression? (Such as from the GFX-100 or X-T4.)

I get LIBRAW_IO_ERROR returned from unpack(), but I don't want to rely on that -- it could mean other things besides lossy compression. Ideally I'd like to check something in libraw_data_t that says what kind of compression it is, or even just a more general "not supported" indication.

I use labraw_ emu.exe Decompress the CR3 image of Canon 90D，
how to get its resolution multiplied by 2 file size?
note:at present, my command is: - W - 4, but the file size is 186M

I tried to use the compiled unprocessed_raw in the Mac but it it requesting for libSystem.B.dylib. See attached. I can't find that file.

Is it possible to run unprocessed_raw without installation? The intention is to include unprocessed_raw in my application app. So best option would be to have required libraries, dll included in a single executable file.
