# Build dx for the usual platforms into ./bin, auto-incrementing the patch
|
|
# version by 0.0.1 on every build.
|
|
#
|
|
# version.txt holds the currently built version. Each run increments the patch
|
|
# component, then builds every platform with that one version injected via
|
|
# -ldflags, and writes it back. So version.txt always reflects the version of
|
|
# the binaries just built, and all of them carry the same one.
|
|
#
|
|
# Override the platform list to build just one:
|
|
# PLATFORMS="linux/amd64" ./build.sh
|
|
#
|
|
# Windows is not in the list: dx compiles there, but the output leans on a
|
|
# terminal that speaks 24-bit colour and draws U+2588 block characters, so
|
|
# shipping it would promise more than has been tested. PLATFORMS can add it.
|
|
#
|
|
# -s -w drops the symbol table and DWARF info, -trimpath keeps build paths out
|
|
# of the binary; together they roughly halve it. Neither affects a panic trace.
