Build error for Erigon Windows

[josephversace]

I am running into an error trying to build windows binaries. The powershell script fails here.

crawshaw.io/sqlite

blocking_step.c: In function 'unlock_notify_cb':
blocking_step.c:42:2: error: 'for' loop initial declarations are only allowed in C99 mode
for(int i=0; i < nArg; i++) {
^
I have tried modifying the following line in wmake.ps1 but that did not help.

-D CMAKE_C_COMPILER:PATH=""$(Join-Path $chocolateyBinPath "gcc.exe -std=c99")"" `

Anyone able to assist?

Please open a PowerShell prompt and report :

• the output of gcc.exe --version
• the output of choco list --local-only
• the output of ($env:path).split(";")
• check if you have any other version of C/C++ compilers installed

Also report what branch are you trying to build: stable or devel ?

Thank you Andrea,

I was trying to build the devel branch I think. I wanted to use it with ethtx so I need the mainnet_archive with debug mode

I have installed Chocolately now and the updated output is below

PS C:\erigon> choco list --local-only
Chocolatey v0.11.3
chocolatey 0.11.3

Still the same error though.

When you install chocolatey you also need to run
choco install cmake make mingw

And above all remove/uninstall any other version MinGW installed on computer or, at the very least, remove those from %PATH% env variable.

[AndreaLanfranchi]

Ok I see. Problem is your gcc version is too old.
We need at least gcc 10 (sorry we'll amend readme)

I suggest to

• Uninstall your version of gcc (I see you installed mingw) and remove C:\MinGW\bin from %PATH% environment variable
• Install chocolatey package manager following the instructions of bullet 3 in the Windows section
• eventually retry the build

Thank you. That solved it. Appreciate it,
