Build explorer failed on Monero v18

[itadashi]

Hi,

I try to build the onion-monero-blockchain-explorer on Ubuntu 20.04 with last monero.
I have this error message when trying to make :

[ 4%] Building C object src/crypto/CMakeFiles/mycrypto.dir/rx-slow-hash.c.o onion-monero-blockchain-explorer/src/crypto/rx-slow-hash.c:52:3: error: unknown type name ‘CTHR_MUTEX_TYPE’ 52 | CTHR_MUTEX_TYPE rs_mutex; ... onion-monero-blockchain-explorer/src/crypto/rx-slow-hash.c: In function ‘me_rx_reorg’: onion-monero-blockchain-explorer/src/crypto/rx-slow-hash.c:163:3: warning: implicit declaration of function ‘CTHR_MUTEX_LOCK’ [-Wimplicit-function-declaration] 163 | CTHR_MUTEX_LOCK(rx_mutex); | ^~~~~~~~~~~~~~~ make[2]: *** [src/crypto/CMakeFiles/mycrypto.dir/build.make:63: src/crypto/CMakeFiles/mycrypto.dir/rx-slow-hash.c.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:286: src/crypto/CMakeFiles/mycrypto.dir/all] Error 2 make: *** [Makefile:84: all] Error 2

I try with devel branch also, but same error.
Thanks for the help :-)

Did you checkout Monero v18 branch from its git?

[itadashi]

Yes in folder monero, i did a git checkout.
Few months ago, i was able to build the explorer.

[moneroexamples]

I can confirm the issue. Let me see what has happened.

[itadashi]

Cool, thanks :-)

[moneroexamples]

I pushed temp fix for the issue into devel branch of the explorer:

https://github.com/moneroexamples/onion-monero-blockchain-explorer/tree/devel

Could you please checking it out?

[deverickapollo]

Saw this issue yesterday working on an integration. Can confirm the fix on the devel branch resolved build issues.

[itadashi]

Thanks @moneroexamples it works :-)
You Temprorry disabled randomx code generation till figure out what exactly is happening, does it affect the functioning of the explorer?

[moneroexamples]

No, unless you run it with --enable-randomx flag.

[itadashi]

Ok great and what is the purpose of this flag exacltly?

[moneroexamples]

randomx is mining algorithm in monero, which is based on randomly generated code that miners execute. With the flag, the explorer was showing the code. But there have been recent backward incompatible changes to randomx, and it broke in the explorer. Haven't managed to fix it yet.

[itadashi]

randomx is mining algorithm in monero

Yeah off course i know it ;-)

With the flag, the explorer was showing the code

Ok i see thanks for the explanation
So we can close the issue for now?
@moneroexamples thank you again!
