Arch Linux User Repository

My extremely limited coding skills and mental facilities are normally just enough for messing things up, no more, no less. This time I did manage what I wanted (i.e., to get wxemedit to run on my system), but I may have messed up something else on said system without even knowing. The instructions below come with no warranty. With that out of the way:

1., Download https://github.com/unicode-org/icu/releases/download/release-77-1/icu4c-77_1-Fedora_Linux40-x64.tgz and extract it to the root of your filesystem (you'll need to sudo to root user first).

2., In the file /usr/local/include/unicode/char16ptr.h, in line 271 replace

template<typename T, typename = std::enable_if_t<std::is_same_v<T, UChar>>>

with

template<typename T, typename = std::enable_if_t<std::is_same<T, UChar>::value>>

in line 273, replace

if constexpr (std::is_same_v<UChar, char16_t>) {

with

if constexpr (std::is_same<UChar, char16_t>::value) {

in line 386 replace

std::is_convertible_v<T, std::u16string_view>

with

std::is_convertible<T, std::u16string_view>::value

You'll not be able to save your changes unless you are acting as root (and yes, knowledgeable people use diff files and the patch command, but I am not knowledgeable).

3., Download the wxmedit aur package. I used the yay command

yay -S wxmedit

which would fail, but at least get the sources for me.

4., Navigate to $HOME/.cache/yay/wxmedit/src/wxMEdit-3.2/configure and edit that file to replace

#CXXFLAGS="-O2"


my_cxxflags_bak="$CXXFLAGS"
CXXFLAGS="$CXXFLAGS -std=c++11"
{ $as_echo "$as_me:${as_lineno-$LINENO}: checking whether -std=c++11 is supported" >&5
$as_echo_n "checking whether -std=c++11 is supported... " >&6; }

i.e., lines 7265 to 7269 with

LDFLAGS="-L/usr/local/lib -Wl,--copy-dt-needed-entries"
CXXFLAGS="-O2"
my_cxxflags_bak="$CXXFLAGS"
CXXFLAGS="$CXXFLAGS -std=c++17"
# { $as_echo "$as_me:${as_lineno-$LINENO}: checking whether -std=c++11 is supported" >&5
# $as_echo_n "checking whether -std=c++11 is supported... " >&6; }`

(Knowledgeable people do not edit configure files directly, of course....)

5., Navigate to the directory $HOME/.cache/yay/wxmedit and issue the commands

makepkg -e
sudo -U wxmedit-3.2-1-x86_64.pkg.tar.zst`

in the above sequence.

6., For the shared libraries in /usr/local/lib to be found by the system (and wxmedit to actually launch), you'll also need to issue the following to commands:

echo "/usr/local/lib" | sudo tee /etc/ld.so.conf
sudo ldconfig

in the order above.

In hindsight, I might have been able to solve the issue without extracting the release-77-1 version of icu on my system ― that is, I might have been better of if I had just modified /usr/include/unicode/char16ptr.h (and $HOME/.cache/yay/wxmedit/src/wxMEdit-3.2/configure). Then again, I just don't feel like undoing all the modifications I have made. Still, I (and you, if you decide to follow the instructions above) will have to watch out for the time when a version newer than 77.1 of icu turns up in the official Arch Linux repo (https://archlinux.org/packages/core/x86_64/icu/).

Hope this helps (or at least doesn't do too much harm).

Anyone else?

oops, it is in community repo, not aur.

used appimage install. there are three versions. the VinnyVynce one is the one that works for e in appimagge. Installed it via bauh, in the aur.

tried applying the outstanding pull request from git but still wont build.

gives error on wxgtk, won't build

launch gives error: $ wxmedit wxmedit: error while loading shared libraries: libicui18n.so.65: cannot open shared object file: No such file or directory

Installing ICU 65 fixes it, but says it should work with ICU>4.3

not currently building

Failing to link with the latest libicu* (seeking v60 instead of v61).

wxmedit: error while loading shared libraries: libicui18n.so.60: cannot open shared object file: No such file or directory

With new installed archlinux (4-18), makepkg produces errors when compiling, eg. ['UnicodeString' does not name a type; did you mean ‘Encoding’?] and some with "BreakIterator" declaration.

What to be done with ICU or something else?
