I am trying to build the latest buildroot from git on fedora-40. What I get for menuconfig, is: *** Unable to find the ncurses libraries or the *** required header files. *** 'make menuconfig' requires the ncurses libraries. *** *** Install ncurses (ncurses-devel or libncurses-dev *** depending on your distribution) and try again. *** $ rpm -q ncurses-devel ncurses-devel-6.4-12.20240127.fc40.x86_64 What I get for linux-menuconfig, is: make: Entering directory '/home/stas/src/fdpp-buildroot/buildroot' support/dependencies/check-host-cmake.sh: line 35: [: cmake: integer expression expected support/dependencies/check-host-cmake.sh: line 38: [: cmake: integer expression expected
Here is the fix for menuconfig: diff --git a/support/kconfig/lxdialog/check-lxdialog.sh b/support/kconfig/lxdialog/check-lxdialog.sh index 16cd9a3186..98bc150a0f 100755 --- a/support/kconfig/lxdialog/check-lxdialog.sh +++ b/support/kconfig/lxdialog/check-lxdialog.sh @@ -48,7 +48,7 @@ trap "rm -f $tmp" 0 1 2 3 15 check() { $cc -x c - -o $tmp 2>/dev/null <<'EOF' #include CURSES_LOC -main() {} +int main() { return 0; } EOF if [ $? != 0 ]; then echo " *** Unable to find the ncurses libraries or the" 1>&2

Did you manage to fix it? If yes, can you please share the solution?
There was something wrong on my side, I suppose. Maybe the CFLAGS var was mistakenly exported with -Werror parameter. I rechecked all my fixes now, and they are not needed, eg missing `int` before `main` only produces the warning, so ncurses are now working again.
Indeed, ncurses is working again. What about the error in comment #2? Is it working for you? I have fedora 40 too, but after running `make` I still get an error: Unknown option 'passive-ftp' make: *** [package/pkg-generic.mk:179: /buildroot/output/build/host-pkgconf-1.6.3/.stamp_downloaded] Error 1
Ah, completely forgot about this one! Since menuconfig now works, please navigate to "Build options" -> "Commands" -> "Wget command" and remove "passive-ftp" from there.
stsp, All, Thanks for the report. The menuconfig issue has been fixed with commit a6210d28db (kconfig/lxdialog: fix check() with GCC14). As for the wget issue, please refer to the release notes of your distribution: https://docs.fedoraproject.org/en-US/fedora/latest/release-notes/ Quoting: The wget command in Fedora 40 uses Wget2. Amd a little trivial web-search turns up: https://fedoraproject.org/wiki/Changes/Wget2asWget And of course, it all quickly leads to: https://gitlab.com/gnuwget/wget2/-/wikis/Home#different-behavior-of-wget2 The current workaround is indeed to remove --passive-ftp from the wget command line, but thisis not a vial long-term solution, because it means it is no longer possible to do ftp downloads (which although legacy, still exist). The proper solution would be to contribute a patch that solves the issue. I think a good solution would be two fold: - introduce a new download backend specifically for ftp - drop --passive-ftp from the default wget command line Regards, Yann E. MORIN.
How about just switching to curl, instead of playing around the legacy stuff as wget is? Ok maybe wget2 is not legacy, but you never know, as now debian-based distros will have wget1, and fedora-based - wget2, all under the same name.
Hello. > How about just switching to curl, instead > of playing around the legacy stuff as wget is? 1. wget is not legacy. cURL and wget were initialy released at about the same period, in 1996 [0] [1]; both saw their latest release in March 2024. Hard to say that wget is legacy without saying so for cURL. [0] https://en.wikipedia.org/wiki/Wget => January 1996 [1] https://en.wikipedia.org/wiki/CURL => November 1996 2. cURL can be configured without FTP support [2], so if switching from wget to wget2 was done, knowing that FTP was dropped, and considering that was acceptable on the basis that FTP is legacy (broken, insecure...), then it is not inconceivalbe that distros may consider truning FTP off in their builds of cURL, ion the same basis (broken, insecure...). Switching to cURL would not solve the issue. Yes, it is a bit far-fetched, but given the reasoning behind wget2 switch, it is legit to consider it for other tools that are not FTP-only. [2] https://github.com/curl/curl/blob/master/configure.ac#L631 3. Existing packages (in external trees) may use wget's authentication options yo authenticate to an HTTP server; switching to cURL would break them. That also applies to existing (def)config files that use non-standard options, like --no-proxy to talk to internal servers, or --load-cookies with a pre-build script that authenticates against an internal server or filled by a CI/CD job, etc... 4. For all things HTTP-related, wget2 is expected to be option-compatible with wget. 5. As a consequence, it feels more appropriate to keep using wget for HTTP/S downloads, and use a tool dedicated to FTP for FTP downloads, and implemented as a separate backend in Buildroot.
