compiling in windows 10

[H S]

having a hard time compiling in RTL433 in windows 10

trying to follow the procedure from 

https://github.com/merbanan/rtl_433/blob/master/docs/BUILDING.md

but the file

FindLibUSB.cmake

is not in the most recent source from 

 https://github.com/steve-m/librtlsdr

eventually downloaded from 

https://github.com/librtlsdr/librtlsdr

but not sure if it's equivalent.

everything else done as indicated but getting errors compiling:

C:\librtlsdr-master\build>cmake -G "MinGW Makefiles" ../

-------------------------

I can provide the log as well if needed

Can you pinpoint what is wrong? 

or is there an up to date windows version compiled available ?

There used to be a source but the link is dead now.

Thanks!

total rabbit hole, tried this last year, tried again tonight, I can only get to 90% . use this librtlsdr(got me past errors building librtlsdr)

librtlsdr-0.6.0

findlibusb.cmake

i ended up using the mingw64\x86_64-w64-mingw32\include folder instead of the mingw64\include

last year I ended up compiling it with visual studio ,but damn if I havent forgotten how

5 hours later......"rabbit hole" lol

will be keeping an eye out too see if you figure it out

[Christian Z.]

For our build checks and releases we compile with both of: MSVC on Windows (native) and MinGW-w64 on Linux (Cross-build). You can see the steps in our .github/workflows/release.yml file.

Using MinGW-w64 on Windows should work too, but we don't have an automated test.

Try a build with "-DENABLE_RTLSDR=OFF" first, to get just rtl_433 to compile, then include rtlsdr later (and SoapySDR, OpenSSL if you need).

The error you got is about MSVC flags (/MP /wd4251 /wd4503) not working in MinGW -- I guess the configuration from the librtlsdr introduces those.

getting it done vid

Great! Thanks!

So just to be clear, I should use :

Source from librtlsdr

https://github.com/steve-m/librtlsdr/tags

mingw32\include folder

Anything else xxxxx32 over xxxxx64

-DENABLE_RTLSDR=OFF. (haven't checked yet - in which file should this be modified?)

I don't expect to compile on a regular basis but wow is this time consuming...

There is no such thing as a precompiled windows version repository, right?

Thx.

[H S]

Also, I see the following in the previous comment "went back and turned off soapy & OpenSSL ,turned on Rtl-sdr.."

How do I turn off soapy & OpenSSL ?

Editing a config file I guess but not sure which one/where...

Thanks for your support.

[Christian Z.]

SoapySDR and OpenSSL are off by default (unless found). Those "-D" are cmake options.

But yes, we do have release builds: https://github.com/merbanan/rtl_433/releases

[H S]

Thanks, for some reason I couldn't trace back the release builds link....

Anyways, I'll have a working process to compile if needed ;)

Cheers,

[Christian Z.]

Anyways, I'll have a working process to compile if needed ;)

Always good to test and see more different ways to build/deploy/use. Thanks!
