pa_stable_v190700_20210406 fails to compile on RPi4

[juanitotc]

Using gcc-10.2 to compile pa_stable_v190700_20210406 with:

CC="gcc -flto -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe" CXX="g++ -flto -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe" ./configure --prefix=/usr/local --disable-static --localstatedir=/var --enable-cxx

..the build fails with:

libtool: link: /usr/local/bin/nm -B  src/common/.libs/pa_allocation.o src/common/.libs/pa_converters.o src/common/.libs/pa_cpuload.o src/common/.libs/pa_dither.o src/common/.libs/pa_debugprint.o src/common/.libs/pa_front.o src/common/.libs/pa_process.o src/common/.libs/pa_stream.o src/common/.libs/pa_trace.o src/hostapi/skeleton/.libs/pa_hostapi_skeleton.o src/hostapi/alsa/.libs/pa_linux_alsa.o src/hostapi/oss/.libs/pa_unix_oss.o src/os/unix/.libs/pa_unix_hostapis.o src/os/unix/.libs/pa_unix_util.o   |  | /usr/local/bin/sed 's/.* //' | sort | uniq > lib/.libs/libportaudio.exp
./libtool: eval: line 1: syntax error: unexpected "|"
make: *** [Makefile:171: lib/libportaudio.la] Error 2

If I manually execute the command without the double "| | " it works.

cmake builds without error, but without library symlinks and without the cxx library.

@juanitotc - thanks for reporting this.

..the build fails

We have several build mechanisms. What commands are you using to build PortAudio when it fails?
Are you using:

./configure && make

or the cmake commands here?

[juanitotc]

I'm using configure (with flags as per the first post) && make when it fails.

cmake && make does not give the same error

[philburk]

Thanks. I did not see the .configure at the end of the command.

[philburk]

I pulled the current PortAudio and it builds using:

./configure && make

bin/paex_sine make no sound from the default 3.5 mm jack.

When I connect a Scarlett 2i2 then a get about a 1/4 second of noise and a bunch of ALSA messages
about an underrun from pcm.c:8424

[philburk]

I then tried the command from above:

CC="gcc -flto -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe" CXX="g++ -flto -march=armv8-a+crc -mtune=cortex-a72 -Os -pipe" ./configure --prefix=/usr/local --disable-static --localstatedir=/var --enable-cxx

It compiled without error on an RPi4 running Raspbian.

[philburk]

I then compiled pa_stable_v190700_20210406.tgz from https://files.portaudio.com/download.html

I compiled using the CC=... command from the previous comment and it compiled fine.

[philburk]

On my RPi4, the line that breaks above is:

libtool: link: /usr/bin/nm -B  src/common/.libs/pa_allocation.o src/common/.libs/pa_converters.o \
src/common/.libs/pa_cpuload.o src/common/.libs/pa_dither.o src/common/.libs/pa_debugprint.o \
src/common/.libs/pa_front.o src/common/.libs/pa_process.o src/common/.libs/pa_stream.o \
src/common/.libs/pa_trace.o src/hostapi/skeleton/.libs/pa_hostapi_skeleton.o \
src/hostapi/alsa/.libs/pa_linux_alsa.o src/hostapi/oss/.libs/pa_unix_oss.o \
src/os/unix/.libs/pa_unix_hostapis.o src/os/unix/.libs/pa_unix_util.o  \
  | sed -n -e 's/^.*[	 ]\([ABCDGIRSTW][ABCDGIRSTW]*\)[	 ][	 ]*\([_A-Za-z][_A-Za-z0-9]*\)$/\1 \2 \2/p' \
  | sed '/ __gnu_lto/d' | /bin/sed 's/.* //' | sort | uniq > lib/.libs/libportaudio.exp

So the difference is that I have a bunch of sed commands in my line where you have "| |".

So the reason it is failing may be because of differences in our setup.

@juanitotc - What OS are you using? Have you recently updated?
When I use uname I get this.

$ uname -a
Linux neuhaus22 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux

Are you still seeing the problem?

[juanitotc]

I'm using piCore64:

uname -a
Linux boxrpi4 6.1.25-piCore-v8 #1 SMP PREEMPT Sat Apr 29 12:41:30 EDT 2023 aarch64 GNU/Linux

Using a more recent version (piCore64-14.x) with gcc-12.2, with the same configure and make string, things work without errors.
