I am trying to compile the BOINC Client on a Ubuntu 23.10 and got an error message while I ran configure.

checking for wx-config... no
configure: error: No suitable wxWidgets library found.

$ sudo apt install libwxgtk-webview3.2-1
libwxgtk-webview3.2-1 is already the newest version (3.2.2+dfsg-4).

$ sudo apt install libwxgtk-webview3.0-gtk3-dev
E: Unable to locate package libwxgtk-webview3.0-gtk3-dev
E: Couldn't find any package by glob 'libwxgtk-webview3.0-gtk3-dev'

--------------------------------------------
If I run try to build on a Ubuntu 22.04 system

checking for wx-config... /usr/bin/wx-config
checking for wxWidgets version >= 3.1.3... no (version 3.0.5 is not new enough)
configure: error: No suitable wxWidgets library found.

$ sudo apt install libwxgtk-webview3.0-gtk3-dev
libwxgtk-webview3.0-gtk3-dev is already the newest version (3.0.5.1+dfsg-4).

sudo apt install libwxgtk-webview3.2-1
E: Unable to locate package libwxgtk-webview3.2-1
E: Couldn't find any package by glob 'libwxgtk-webview3.2-1'

In both case I am not able to proceed.

I notice that there was a similar discussion before on a similar issue
https://boinc.berkeley.edu/dev/forum_thread.php?id=13933&postid=100664#100664

here is where I have listed everything I needed to get everything to work.

sudo apt find

is what is used to find the packages containing what I needed.

I am able to build the client

~/boinc/boinc/client$ ls -alg boinc_client
-rwxrwxr-x 2 fckwan 3970264 Jan 26 19:14 boinc_client

But I got the following error message when I execute the client.

26-Jan-2024 19:47:15 [---] GUI RPC bind to port 31416 failed: 98
26-Jan-2024 19:47:16 gstate.init() failed
Error Code: -180

I found the following website.

But I got the following error message when I execute the client.

26-Jan-2024 19:47:15 [---] GUI RPC bind to port 31416 failed: 98

I have always been able to start from the boinc icon under the system menu. My understanding is that you have to start the client and the manager if you are using one from the same directory. Don't know if this link given in the link you give is any help if you are not using a gui on the machine in question.

I only build the boinc-client. May be I will need to build the boinc and start a the same time.

If you don't want to use any GUI to check on this BOINC from a remote location, you can also start BOINC without any GUI RPC:
boinc --no_gui_rpc is the suggestion in the link I posted if you are not using a gui.

I only build the boinc-client. May be I will need to build the boinc and start a the same time.

If you only build the client, you shoudn't be getting any warning for wx-widgets. The gtk and widgets libraries are only needed for the manager

./_autosetup
./configure --disable-server --disable -manager --enable-client
make
